Re: [Paraview] Surface representation inconsistency
Hello. For the first issue, I don't know. For the second issue, the Gouraud lighting is active only on surface with normals. Paraview considers data as 3D volume, even if you are reading surface data. So, you have to use the Extract Surface filter, then the Generate Surface Normals fiter. Gouraud lighting would be applied on the Generate Surface Normals object. 1. Inconsistent rendered images between still and interactive as shown in the first two pictures. It should be showing the muscle blockset during interaction instead of the skeletal blockset. It appears that last known render is still presiding in the memory during interaction. How can I flush it? 2. Inconsistent lighting effect on different objects as depicted in the last image. Changing from Flat to Gouraud does not affecting the left side object, it still would apply Flat lighting, which in turn causing it to appear pixelated.

Re: [Paraview] Surface LIC Problem
Hello. What are these non-zero surface vectors without slipping or moving walls ? With NS solvers, the velocity vector in an axis system bound to a wall should ALWAYS be zero at the wall (moving wall or not moving wall): this is the adherence condition. As LIC needs a non zero vector at the wall in an axis system bound to the wall, you cannot use the velocity vector, and you MUST use the skin friction vector. My NS solver gives the three components of the skin friction vector in an axis system bound to the wall as three scalar arrays. So I have to use the PV Calculator filter in order to build the vector array from these three scalar arrays, something like Friction_vector = x_component*iHat+y_component*jHat+z_component*kHat But you may also use the Calculator filter to build the friction vector from the stress tensor and the normal vector at the wall. It depends on the output of your solver. Richard Le 14/02/2014 14:34, Magician a écrit : Hi Burlen, Richard, Utkarsh, Thanks for your advices. I misunderstood that the Surface LIC Plugin should calculate some kinds of the vector fields on surfaces.

Re: [Paraview] Surface LIC Problem
Hello Which vector field are you using with LIC ? The LIC control panel allows to choose the vector to be used, and you MUST choose a vector field that is NOT ZERO on the surface. With Euler CFD results, the velocity vector is not zero at the wall, and you can use this vector. With Navier-Stokes CFD results, the velocity vector is zero at the wall, and you have to use the skin friction vector instead. Richard I'm trying the Surface LIC Plugin. My models are formatted as VTK MultiBlock Dataset, and there are geometries of fluids and walls. I'd like to visualize LIC on the walls. First I applied Surface LIC to the walls, the results are something wrong. Next to the fluids, they are OK. But there are extra walls which I don't want to visualize (ex. Inlets/Outlets, external boundaries). Maybe the reason of the walls are that they don't have the velocity values of main flows. I also tried the Resample with Dataset filter for linking main flows to the walls. The results are roughly good, but sometimes the resampling qualitys are poor (dropping the values). Is there a good way to visualize the part of the walls' LIC? My sources have complicated shapes, so I want to make the best use of the information of blocks of walls. -- Richard GRENON ONERA Departement d'Aerodynamique Appliquee - DAAP/ACI 8 rue des Vertugadins 92190 MEUDON - FRANCE phone : +33 1 46 73 42 17 fax : +33 1 46 73 41 46 mailto:richard.gre...@onera.fr http://www.onera.fr ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
Re: [Paraview] Performance of the CGNS Reader
Thank you for this answer, Mickael. My 1.36 Gb CGNS dataset is built from structured meshes and Paraview should not 'eat' too much memory. I have checked that enabling multi-core in Paraview does not change anything: PV always needs about 15 mn to load my dataset, same loading time as without multi-core. I think that the loading time ratio 15 mn / 1 mn for PV against Tecplot remains too high, even if PV parses the file two times. If Tecplot takes advantage from multi-core (I don't know), the loading time ratio between PV and Tecplot should not excess 8 when using 4 CPUs. A ratio of 15 leading to 15 mn of loading time or more for larger datasets is unacceptable for interactivity. So PV is unusable for large CGNS datasets, unless using batch mode. I think that an effort in redesigning the CGNS reader would be welcome. Best regards. Richard Le 29/08/2013 20:55, Mickael Philit a écrit : Hello, First, the CGNS reader coming through the VisItBridge is not working in parallel, it's a plain serial reader. Second, there are limitations to the current cgns reader way of doing thing, since : - At the beginning, it parses the whole file (this takes a lot of time) to get variable names, blocks and so on, before actually reading the data. [ I think that tecplot is cleaner because it seems to read the whole CGNS file in one pass ] - meshes are read in a temporary array and converted to a VTK vector of coordinates (thus memory manipulation) - for unstructured meshes, convertion from 'integer' to 'long' of cells connectivity eats memory. The CGNS reader can improve but at the cost of redesining some parts to fit better in paraview and go for parallel.

Re: [Paraview] Paraview can't read Tecplot X,Y(X) files
Hello. If you are using I=20, J=2 and K=1, you should have 20x2x1=40 points in your mesh (it is a surface), so you should have 40 lines after the ZONE line. Paraview finds only 20 lines and assumes zero for the 20 missing values. So you have to repeat your 20 data lines at the end of your file. Also, you should not have all X,Y,Z variables to zero because Paraview cannot display the mesh. For instance, you may define a surface grid assuming X=Distance for all your data. Then you should have Y=0 for the first 20 data lines, and Y=non zero constant for the next 20 data lines while keeping same X, Distance and Temperature values as in the first 20 lines. The variable Z may be kept to zero for all lines. Thus, your mesh will look like a rectangle. Le 18/07/2013 16:18, M. a écrit : Hello Richard, Thanks for your answer.

I'm using some examples from this site: http://people.sc.fsu.edu/~jburkardt/data/tec/tec.html http://people.sc.fsu.edu/%7Ejburkardt/data/tec/tec.html The 3D examples are read correctly in Paraview, but the examples http://people.sc.fsu.edu/~jburkardt/data/tec/simpxy.dat http://people.sc.fsu.edu/%7Ejburkardt/data/tec/simpxy.dat and http://people.sc.fsu.edu/~jburkardt/data/tec/simpxy2.dat http://people.sc.fsu.edu/%7Ejburkardt/data/tec/simpxy2.dat are read but can't be plotted. All the statistics are N/A (Type, Number of Cells, Number of Points), no bounds are recognized, and the Spreadsheet view is empty. Is this a bug? Hello. Paraview is a 3D software that is always expecting a mesh (surface or volume) with the three X, Y, Z variables for points coordinates. Your simpxy.dat file has only two data variables (Distance and Temperature), that is why it cannot build points and cells and shows N/A (Not available). Try to add coordinates of a grid to your file, and you should be able to plot Temperature against Distance. -- Richard GRENON ONERA Departement d'Aerodynamique Appliquee - DAAP/ACI 8 rue des Vertugadins 92190 MEUDON - FRANCE phone : +33 1 46 73 42 17 fax : +33 1 46 73 41 46 mailto:richard.gre...@onera.fr http://www.onera.fr -- Richard GRENON ONERA Departement d'Aerodynamique Appliquee - DAAP/ACI 8 rue des Vertugadins 92190 MEUDON - FRANCE phone : +33 1 46 73 42 17 fax : +33 1 46 73 41 46 mailto:richard.gre...@onera.fr http://www.onera.fr ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview

Re: [Paraview] ??????RE: error when open tecplot(.plt) files
Hello. Glad to see that you have solved your problem. It is true that you need the Vislt software for reading Tecplot files, but this software is included in the last Paraview release 3.98.1. I am using the last binaries found on the Paraview download pages, and I can read Tecplot binary or ASCII files without adding software. On older Paraview releases, the Vislt software was delivered as a plugin that was not activated by default. In that case, you had to go through the menu Tools-Manage plugins, then select the Vislt plugin, click the Load selected button, close Paraview, and finally reopen Paraview to get the plugin activated. So, check your Paraview version, and you may want to update it for the last 3.98.1 release. But take care: there are two Tecplot readers. If you open a (.tp) ASCII Tecplot file, you will have the choice between Tecplot Files or Tecplot Files (Vislt). I don't know exactly what are the differences, but if a reader fails, try the other. But the Tecplot readers are not perfect, and that may explain your ERROR message. Sometimes, with Tecplot ASCII files, I have to remove from the header some options that the readers do not recognize. Try to have the simplest headers without exotic options when using ASCII files, and the readers will be OK. If you have again problems with (.plt) files, feel free to provide a (short) sample file.

Re: [Paraview] ?????? ??????RE: error when open tecplot(.plt) files
Hi Zhang. Just a last info: since my last mail, I have made some tests with old binary Tecplot (.plt) files, and I discovered that some files are readable, but some files are not readable and give the same error message. In fact, it depends on the Tecplot version that has built these files. So, if you have problems with old (.plt) files, you may try to convert them into a recent version of the (.plt) format using a recent Tecplot release before reading them with Paraview. Have a good week-end. Richard. Le 26/04/2013 14:20, zhangqingyu a ??crit : Hi Richard, Thank you again for your patient and useful suggestion!

[Paraview] Paraview 3.98.0 new behavior of Vislt Tecplot Reader
Hello. I have just tried the new PV 3.98.0 Linux release and found a new annoying behavior of the Vislt Tecplot Reader. I read a pvsm state file built with PV 3.14.1 and all rendering fails! With PV 3.14.1, I get one object in Surface mode colored by the pressure variable, and another object in Surface LIC mode using the friction vector and colored by the friction modulus variable. But with PV 3.98.0, I get only solid color representation for the first object, and solid color with points representation for the second object, with many errors in the message window. Looking at the information tab of the visible objects, the variables (pressure, friction vector, etc...) are not present ! My data files are Tecplot Files that should be read with the Vislt Tecplot reader. Looking at the reader property tab, I found two options in the Meshes frame: mesh and points/mesh. The points/mesh option does not appear in PV 3.14.1. Both options are checked in PV 3.98.0 when reading a state file built with PV 3.14.1. Unchecking this points/mesh option makes rendering OK. I tried further tests with other Tecplot files in PV 3.98.0 without starting from a state file. I tried to open either a file that requires the classic Tecplot reader, or a file that requires the Vislt Tecplot reader: - when the classic Tecplot Reader is required, all is OK. - when the Vislt Tecplot reader is required, only the points/mesh option is checked by default, so it should be unchecked and the mesh option should be checked if I want a surface mode colored by a variable or a Surface LIC mode. So, my question is : what is this new points/mesh option in the Vislt Tecplot reader, and why is it checked by default ?

Re: [Paraview] Paraview 3.14.1 Tecplot Reader Errors
Hello I don't know how to make this with a command line, but you may read your ASCII file, then use the menu File-Save Data, select the VTK file type, and you will have a popup window with some options: - Data mode: ascii, binary or appended (default). - Compressor: None (default) or Zlib May be this could be automated with a Python script.

While we are hoping that Paraview developers resolve this problem and accomplish a usable Tecplot reader, I may rewrite a code to output my data as legacy .vtk ASCII files. May I ask you a question? it is probably simple: how to convert a legacy .vtk ASCII file to a binary file. Tecplot provides such a command line tool, preplot, which compresses data greatly before loading into Tecplot, otherwise uncompressed data could eat up all the memory quickly. For my own large scale simulation of particles, one snapshot generates as much as 14GB data for Tecplot, and preplot shrinks them to 2GB! I will run Paraview in parallel processing mode, but it is always optimal to compress ASCII data into binary before loading them into Paraview.

Re: [Paraview] Paraview 3.14.1 Tecplot Reader Errors
Hello. Your Tecplot file is written as an Unstructured grid with quadrilateral elements. The Tecplot reader in Paraview cannot read this: it assumes that the file contains a MultiBlock Structured grid (with 3 index I, J and K for a volume, or only two index I and J for a surface) When I see your image, I think that you can write your grid in a Structured format. Moreover, a file header is missing. You should have a header with two lines: line for the title end a line for the variables: TITLE=SOMETHING VARIABLES=X Y Z Richard. -- Richard GRENON ONERA Departement d'Aerodynamique Appliquee - DAAP/ACI 8 rue des Vertugadins 92190 MEUDON - FRANCE phone : +33 1 46 73 42 17 fax : +33 1 46 73 41 46 mailto:richard.gre...@onera.fr http://www.onera.fr ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
[Paraview] Asking for Tecplot reader improvements and a sample Tecplot file for Unstructured Grids
Hello, The Tecplot reader is very usefull, but it should be further improved because many Tecplot files (written by the user according to Tecplot format specifications or written by Tecplot itself !) still cannot be read ! I am usually using Structured grid, and the Tecplot reader works fine for most of my ASCII files, except for those that are written by Tecplot itself and that contain the STRANDID and SOLUTIONTIME tokens that are currently unsupported. I have to remove these unsupported tokens from all ZONE headers before reading with Paraview. May I suggest to ignore those unsupported tokens with just a warning rather than stopping reading ? Another problem is with Unstructured grids. Reading the mail of Beichuan Yan (subject =Paraview 3.14.1 Tecplot Reader Errors ), I tried to read several ASCII Tecplot files with unstructured grids. Some of my files made Paraview freeze, other could not be read and gave many error messages such as : The record type XXX found in the file is unknown where xxx may be some coordinate data or something else. It seems that the reader is bad positioned in the file because one or more token in the ZONE header are not recognized. Looking at the reader source file, I tried to modify the header of simple Tecplot files with TRIANGLE or QUADRILATERAL elements, but I never succeeded in identifying which token is not recognized. So, at that time, is the Tecplot reader really able to read unstructured grids or not ? If yes, could someone provide a sample Tecplot file for unstructured grid that Paraview can read ? This would help identifying what is not well recognized in the true Tecplot format. Thank you in advance for your help.

Re: [Paraview] Help Need in Streamline for CGNS file
Hello. For streamlines on a curved surface, you should get better results using the SurfaceLIC plugin. First, you have to load this plugin through the menu Tools-Manage plugins: select the SurfaceLic plugin, then click on the Load selected button. You can also click on the little cross before SurfaceLIC and check the AutoLoad check box: thus, the plugin will be loaded each time you start Paraview. Then, you should have a velocity Vector in your dataset. If you have not, build a vector from three scalar components using the Calculator filter. When you have a vector data, the Surface LIc item is available in the list of representation mode. Select it and you will get a picture that looks like an oil flow visualization. You can adjust some LIC parameters in bottom of the Display tab. You can choose another vector if you want because LIC uses by default the first vector that it finds, and it may be the normal vector.

Re: [Paraview] PV 3.14.1 crashes when disconnecting a dataset
Thank you for this info, Utkarsh. Maybe your are right, my problem could be related to this discussion. But I have never tried to load a state file AFTER having added some source or other data in the pipeline. When I load a state file, it is always on an empty pipeline, and I never got PV crash when loading a state file on an empty pipeline, even if it is a complex state file. The problem appears only when I want to disconnect to get the pipeline empty: PV may crash or not, depending on the complexity of the current pipeline. I will take a look at the next binaries release to see if my problem is solved with your patch. Best regards.

Re: [Paraview] Oilflow - Surface flow
Hi Lorenzo. If your data are the results of a CFD computation, the surface velocity should be non zero when solving Euler equations with wall slip conditions, or zero everywhere when solving the Navier-Stokes equations with wall adherence conditions (non slip). But when solving Navier-Stokes equations, you should get a skin friction vector (local tangential force) that is non zero: for LIC to give an oilflow pattern, you should use this skin friction vector instead of the velocity vector. And please, could you tell us what was the solution given by Koen? His mail was missing. Richard. Lorenzo a écrit : Thanks both of you, your help is really appreciated! @ Richard: as I'm using the non slip condition for my walls geometry, the velocity on the surface is 0 everywhere… Just checked and the vector I get with the calculator is made by zeroes only… so, what is not clear to me, is how do I give the LIC a vector which is not zero? @ Koen: that worked.

[Paraview] Clip on Extract Subset crashes when Extract Subset reduces to a surface

Here is an example tested on PV 314 : - Loading a structured IJK domain (Tecplot reader or else), say Imax=40, Jmax=8 and Kmax=20 - Add the Extract subset filter to get the surface J=0, so subset indexes are I from 0 to Imax, J from 0 to 0, K from 0 to Kmax - Add the Clip filter with plane Z=something = Crash !!!

Re: [Paraview] Oilflow - Surface flow
Lorenzo. There is a LIC parameter that is responsible of the heavy feature when you pan, rotate, zoom, etc.. Look at the bottom of the Display tab of your object that use LIC: you will see the option Use LIC when using LOD. This option is checked by default and makes LIC to recompute the rendering while your are moving the object. Uncheck this option: LIC will be deactivated while you are changing the view and it will render the object only when you will release the mouse button. It may take a while before rendering occurs after mouse button release depending on a parameter in the settings: menu Edit-Settings, select Render View and look at the value of the Lock interactive render parameter: it should be 2 (seconds) by default and you may set it to zero. @David: I think the surface vectors and surface flows filters are meant to address this problem. I have tested these filters together with the Stream tracer with Custom source filter, but I never succeeded in getting full streamlines on the curved surface of an aircraft. I think there is really a problem of projection in the Stream Tracer algorithm. I wonder if this projection is done as it is only a second order modification of the vector direction and it is not needed to follow a stream line in volume. Richard. lovecraft22 a écrit : Thank you Richard. The LIC seems heavy when you pan, zoom in or zoom out your geometry, not in generating the flow paths. What you get is actually really nice. If there no way in getting good streamlines (as you pointed out I got short lines only) then the LIC is fine. Maybe there's a way of generating that directly in openfoam, as there is for free flow streamlines. Thank you again for your time.

Re: [Paraview] Unexpected lines in Surface with Edges mode with PV 3.14
Hi Utkarsh. It seems that you were right: the problem is on my side, due to the settings of my graphic card NVIDIA Quadro FX 1800 on Linux CentOS. As Paraview does not allow to set Antialiasing on, I had set Antialiasing through the control panel of my NVIDIA graphic card and I had selected the Override Application Settings option. But these settings are not taken into account each time I start the PC: starting Paraview without opening the NVIDIA control panel before always gives images without antialiasing (PV 312 or PV 314), and PV 314 shows these unexpected lines in Surface with edges view mode. But if I open the NVIDIA control panel before starting Paraview, look at the Antialiasing setting that is always Override Application Settings and quit the control panel without changing anything, Paraview 312 or 314 gives now clean images with antialiasing... and PV 314 does not show the unexpected lines in Surface with edges view mode !

Hi Utkarsh. No, the behavior of PV 3.12 Linux 64 bits or Windows 32 bits is correct (see my first mail about this subject). The behavior of PV 3.14 is also correct in the Windows 32 bits version. The strange unexpected lines appear only in the Surface with Edges mode of PV 3.14 Linux 64 bits while its Wireframe mode remains correct.

[Paraview] Difference between vector and vector_components
Hello. I think that the right scale mode for arrow glyph should be vector: in this mode, the glyph (the arrow) would be scaled according to the vector magnitude while it remains aligned with the vector. I am not sure but I think that the scale mode vector components means that each component of the glyph would be scaled according to the same component of the vector, so the arrow would be deformed and may not have the same orientation as the vector.

Re: [Paraview] PV 3.14 Linux crashes when trying to open a file
Paul McIntosh a écrit : My 2 cents (sorry for butting in without actually reading the full thread) - I have noticed that states from earlier version of PV are not compatible with 3.14 for some reason. If you resave the state then it works. Hello. For me, the state files from PV312 are almost compatible with PV 314: when opening an earlier version state file, PV 314 just proposes to create an additional view that may be canceled and I recover the full saved state.

Maybe this is due to the new Layout feature ? That shouldn't affect it. I remember ensuring that the layout xmls are compatible. Can you share a state file to reproduce this issue? I'd like to have it addressed. Utkarsh Utkarsh, the state files that I used cannot be shared because they concern confidential data and the datasets are heavy. Is the state file alone without dataset useful for you ? But I could also try to build a small pvsm test file with test data with PV 312 and see what happens when reading with PV 314, and I will send it on next Monday. In fact, it's not really important (for me) if PV 314 proposes to create an additional view as you can cancel it. More annoying is another problem that I discovered with one of my PV 312 pvsm state files with heavy data sets : PV 314 crashed after selecting the state file while loading the data! I don't know if the crash occurs when PV 314 is trying to create an additional view. But the state file is for a complex pipeline that should produce a 3D view from full CFD data with some surface grids and field cuts in surface mode and some surface grids in surface LIC mode, and two spreadsheet views that show the data in SurfaceFlow objects. I discovered that PV 314 could read a modified state file that was saved by PV 312 after having deleted the two spreadsheet views, and I could create again these two spreadsheet views within PV 314. If the full state file without dataset is useful for you I will sent it on next Monday.

I've tried the CGNS reader included in the PV 3.10.0 final release with several example from the CGNS site http://cgns.sourceforge.net/CGNSFiles.html (delta.cgns, delta_vertex.cgns) and also with my own CGNS files and I always get an error: ERROR: In /home/kitware/Kitware/ParaView-3.10/source/Utilities/VisItBridge/AvtAlgorithms/vtkAvtSTMDFileFormatAlgorithm.cxx, line 118 vtkVisItCGNSReader (0x9ef0b60): Unable to find any meshes ERROR: In /home/kitware/Kitware/ParaView-3.10/source/VTK/Filtering/vtkExecutive.cxx, line 756 vtkPVCompositeDataPipeline (0xab84150): Algorithm vtkVisItCGNSReader(0x9ef0b60) returned failure for request: vtkInformation (0xa21d6f0) Debug: Off Modified Time: 93481 Reference Count: 1 Registered Events: (none) Request: REQUEST_DATA_OBJECT ALGORITHM_AFTER_FORWARD: 1 FORWARD_DIRECTION: 0 Could you give any CGNS example that work?

Re: [Paraview] LIC surface Color by variable lost on Screenshot with offscreen rendering
Hello, Utkarsh. The screenshots I have sent have been made with PV-3.10.0-RC1-Linux-x86_64 on CentOS 5.5. I performed the same screenshot test with PV 3.8.1 on Windows Vista, but I had not this color problem, neither the window over picture problem of Aurélien Marsan.

Re: [Paraview] LIC surface Color by variable lost on Screenshot with offscreen rendering
Utkarsh, I have performed the same screenshot tests on Windows Vista 32 bits with PV 3.10.0-RC1. No problem. The picture is always as expected, with the LIC representation being colored by the pressure variable in bot cases, offscreen rendering checked or unchecked. So the LIC color by variable seems to be lost only with Linux. If this may help you, I noticed something on the 3D view on Vista when I take a screenshot while offscreen rendering is checked: the LIC color by variable is lost for a short time, each block getting a different solid color, then the LIC color by variable comes back on the dataset, and the saved picture is colored by variable as expected. So the problem in Linux could be some kind of time delay, the picture being saved while the 3D view is changing to solid color? Richard Utkarsh Ayachit a écrit : Is this on Windows?

Re: [Paraview] Some tests and questions about PV 3.10.0-RC1
Thank you for your answer, Robert and Sebastien. I have read the wiki page given by Robert and I understand that I have to follow the Opening multiple files method because my files are NOT times series but they are pieces of the skin of an aircraft, or individual 3D CFD blocks. Our CFD software gives one file / block. I agree with the suggestion of Sebastien: if we select multiple files in the OpenFile process, once a reader has been selected for the first file, keep this reader and don't ask for the reader type for following files, unless their extension is not the same. This would avoid to click OK 350 times or more, unless the user has a dataset with 350 different file extensions! :-D Best regards. Richard Sebastien Jourdain a écrit : Hi Richard, I've just talked to Rob about your problem and explained your point. Rob is going to report a bug for that. One solution we were thinking of is when several files are selected in the OpenFile process, if we already have define a reader for a given extension, we reuse that same reader and ask for the reader type only for new extension where concurrent reader exist. What do you think ?

[Paraview] Some tests and questions about PV 3.10.0-RC1
Hello, all. I have just downloaded the PV-3.10.0-RC1 Linux 64 binaries and it works fine. I Could not find the VisIt plugin in the Tools-Manage plugins menu, but I suppose it is now fully integrated in PV? However, I was able to read Tecplot files, and I could also load the LIC plugin. For all and Adriano Gagliardi: I said in a previous mail that the VisIt Tecplot reader in Linux PV 3.8.1 was not working on my new CentOS 5.5 workstation. This problem is now solved with PV 3.10.0-RC1: both proposed Tecplot Readers, Tecplot and Tecplot(VisIt), are working fine. Now I have just a question about rendering. When I rotate or zoom an object, the object rendering is coarse as in previous PV versions, but it remains coarse for a few seconds when I release the mouse, and I see a countdown in the bottom left of the window: Full resolution render in : xx seconds. This is not very important but just a little bit annoying. Is there a parameter in the settings that could reduce this rendering time?

Re: [Paraview] Some tests and questions about PV 3.10.0-RC1
Thank you for the answer, Robert. The Tecplot reader works fine with a single file that contains a multi-block dataset, but I encountered a problem when trying to read the same data as a serie of Tecplot files. Each file is a single block surface grid on the skin of an aircraft. Once I had selected all my files, I got an error message: Group name and proxy must be non empty. But this was only a warning and PV was always running. Then I had to choose between Tecplot Files (VisIt) and Tecplot Files in the Open data with.. window and click OK for each file in my serie. Each time I clicked OK, a new file was loaded in the pipeline, but as I had selected more than 350 files, I decided to cancel. But the Cancel button is ignored and the Open data with.. window appears again and again! The only way to cancel the reading task was to kill Paraview. I hope that this could be solved in the final release. Now may I suggest an improvement for all readers? When reading huge datasets, the screen seems to be frozen (for about one minute with my full aircraft CFD dataset), and it would be nice if we could have in a future release some progress bar or something else indicating that PV is always alive.

[Paraview] Tecplot reader from PV 3.8.1 fails on Linux Redhat CentOS
Hello, all. I have been using Paraview 3.8.1 with the Tecplot reader without a problem on an old HP xw4200 workstation with Linux 64 Redhat 5. The only thing that did not work was the LIC plugin because my graphic card driver was too old. Today, my workstation has been replaced and I have now a Dell T3500 with Linux 64 Redhat CentOS, but the Tecplot reader fails. I get no error message, each array in the dataset is recognized with its correct name, but all values are completely wrong: each array (coordinates or CFD scalars) is in the range [0,9] or [-9,9] and the drawing in the 3D window looks like an aircraft after a crash! The problem appears both with PV 3.8.1 32 bits and PV 3.8.1 64 bits. I am using the binaries from the Paraview download page. Our CFD software produces only Tecplot files and I have a workaround with a small utility that can convert my ascii Tecplot Datasets into ascii VTM Datasets, and at least the LIC plugin works fine on theswe VTM datasets. But translating Tecplot datasets into VTM datasets is very annoying when I am using large CFD datasets for a full aircraft because it duplicates my data and it reduces my free disk space. Does anyone has an idea of what could be done to repair the Tecplot Reader on CentOS?

[Paraview] Saving integrated data on an animated slice
Hello everybody. I am performing Surface flow integrations over the skin of an aircraft and I would like to see how the integration depends on the X coordinate with integrations from the nose of the aircraft to some X moving plane. I am using the Surface Flow filter over a Clip object, and I have animated the X coordinate of the origin of the cutting plane in the Clip object. Using a spreadsheet view, I can see the value of the Surface Flow object changing with the X coordinate, but I don't know how to save the data of the Surface Flow object for all animations steps into a single csv file. I don't want to save the animated pictures, just the animated data into a single csv file for further computations with OpenOffice Calc. I first tried to select the Surface Flow object then File-Save data, but even when I check the Write all time steps box of the Configure Writer dialog box that comes after the dialog box for the name of the file, all I can get in the csv file is the value for the last animation step. Then I tried to select the SpreadSheet view and File-export into a csv file, but this gives the same result. I believe that the Writer is expecting Time series, by my data (the aircraft skin) are not, and animations steps don't seem to be understood as Time steps. Of course, I can save data step by step, each step in a csv file, but does anyone know a trick to save data for all steps into a single csv file.

Re: [Paraview] Saving integrated data on an animated slice
Thanks, John, but I don't know how to use this. Does it need some code writing? I cannot compile PV and I was wondering if saving data from each step of an animated clip on static objects was possible with the last PV 381 binaries. Is there any filter, or maybe Python script to do that? I tried to play the animation in a Python script and use CreateWriter as found on a Wiki page, but it does not work (CreateWriter seems to be for future PV 3.9).

Re: [Paraview] Saving integrated data on an animated slice
Thanks, Adriano. This seems to be a very good idea. I could attach a Programmable Filter script after my Surface flow filter. My script should first create the data file with an append status so that it would not be overwritten at each animation step, then it should output the Surface Flow point value at each step. So maybe two Programmable Filter scripts? The first one before the animated Clip filter to create the output file, the second after the Surface flow filter. Maybe a pipeline like that: - Programmable Filter 1 : Creates the output file with append status. Should execute once! - Animated Clip : X coordinate of the cutting plane origin is animated. - Surface Flow filter: performs integrations and gives a Surface Flow point value. - Programmable Filter 2: write the Surface Flow value. Should execute at each animation step. I will try to do that, but I am not very easy with Python, so if someone can help me to write these two scripts, thanks in advance. Richard.

[Paraview] Normals consistency on a Multi-block dataset of surfaces
Hello all. Could someone tell me if there is a simple way to get Normals consistency over a multi-block dataset that contains only structured surfaces grids? Here is my problem: I have a multi-zone Tecplot file that contains the skin of the right part of an aircraft, so the skin is NOT closed in the symmetry plane. The skin is a collection of structured IxJ ordered surface grids. The orientation of the surface grids are not consistent, some grids having normals pointing outward, other grids having normals pointing inward, and I need all normals pointing the same direction for Surface Flow integration. The Tecplot reader gives a multi-block dataset and I am using these filters for rendering: Tecplot reader-Extract Surface-Generate Surface Normals The Generate Surface Normals filter is used with Consistency property on (the default). Also rendering with light is OK, adding the NormalGlyph filter shows that normals are still inconsistent, each surface grid keeping its orientation, and using the Surface Flow filter with any vector gives bad results. Thank you in advance for any suggestion.

Re: [Paraview] Problems with Surface LIC
Hi all. I have often read here that reverting to older GPU drivers solves LIC problems. Updating a GPU driver is supposed to improve the GPU performance. So if you have a driver that makes LIC work, I am wondering why LIC may fail when updating to the newest GPU drivers?

David E DeMarle wrote: GPU drivers are frequently buggy. It is one of the reasons why they come out so frequently. Thank you for the answer. So the GPU rule seems to be: When you have got a good driver for LIC, please don't update it! :D These are not good news for people depending on system administrators who may have planned periodic GPU updates (although the period between two updates may be very long!) and may have other priorities than searching for the best driver to make a given software run, especially if this is only for a few number of more or less obsolete workstations. This promises again sweat, blood an tears for some poor LIC users... :D But indeed, LIC is a great plugin. I got some pretty pictures on some workstations and on my home computer (with a good driver!).

Re: [Paraview] Reading several Tecplot files at a time
Thank you Berk for this useful script. I had just to modify this line: r.FileNames = full path/myfile%d.tp % tp In fact, it must end with % i which is the index of the loop, not with % tp. And finally a remark: before building the Tecplot files names, it must be kept in mind that the index of the loop starts from 0, not from 1. I first tried this script with only three files (myfile0.tp, myfile1.tp, myfile2.tp). I get many Warning messages from the Proxy manager, but it works. The geometry is not visible after running the script, although it contains the Show command and the eye in the pipeline is not greyed, but it becomes visible when I select the Reset button in the Toolbar. All I have to do now is simply to rename my 300 files that actually don't have following numbers inside their name. Thanks again. Richard. Berk Geveci wrote: This is an interesting challenge. Currently, there is no way of having a reader load multiple files as multiple blocks. You can do time series but not blocks. The following would have achieved that: reader = TecplotReader(FileNames=['myfile001.tp','myfile002.tp']) There is a (slightly hackish) way of achieving what you want. Try the following script: from paraview import servermanager as sm readers = [] for i in range(300): r = sm.sources.TecplotReader() r.FileNames = full path/myfile%d.tp % tp readers.append(r) g = GroupDatasets() g.Input = readers Show(g) Ignore the resulting errors. What I did here is to use the low level ParaView Python API to create 300 readers but not show them in the GUI. I then used the group filter to create multi-block from all of them. This will probably be somewhat slow to execute and also you won't be able to save a working state out of this. Make sure to adjust the line that sets the filename. My code would create filenames like myfile1.tp, myfile10.tp. You'll need some extra logic to add the leading zeros in indices. -berk On Fri, Jul 16, 2010 at 7:12 AM, Richard GRENON richard.gre...@onera.fr wrote: Hello, all.

The default X axis is the Row ID. OK. 2. Now I want to use one of my three data arrays as the X axis: I select the radio-button and the first variable P is selected by default on the list-box. OK, this is the variable I want on the X axis, but I get many error messages because No X column is set (index 0). I have to select another X axis variable, then to come again on the P variable. No more error, but the X axis remains scaled with the Row ID values! I have to uncheck a variable in the line series panel and to check it again to obtain the correct P values on the X axis. Finally I get my three curves and I can change the X axis variable as I want. 3. All variables are scaled by default with the bottom-left axis system and I want to scale one of the variables on the right axis. I select one variable in the Line series panel and I try to change the default bottom-left Chart Axes for bottom-right or top-right axis system. Nothing happens: the top and right axis don't appear and all variables remain scaled on the bottom-left axis system. I can change some attributes of the variable (Line thickness, Line Style, Marker), but not the Chart Axes, although it was possible to change the Chart Axes with PV 3.6.2. I attach the very small csv file that I used for my tests. Regards.

OK, the problem is solved: PV3.8 LIC plugin works on our most recent Linux workstations. I have to convince my boss to replace my old one. Thank you all for your answers.

[Paraview] PV3.8.0 RC1 LIC and VisIt plugins
Hello Two questions about PV3.8.0 RC1: 1. Is there somewhere a how to about using the LIC plugin? Using my own data with a simple 3D structured grid (vts) that has vectors, I extract a 2D grid, then I try to apply the LIC on 2D structured grid filter and PV crashes! Then, trying to reproduce the picture that is on the PV 3.8 news page, I read the disk file, extract a contour, then try to view it as Surface LIC and PV freezes! 2. VisIt plugin: there are two VisIt plugins, one in the plugins folder, one in the lib folder. Which one is the good one?
