[Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files
Hello. PV 3.6.2 crashes on Linux when loading a state file (*.pvsm) that references Tecplot files. Here is my test: -Starting PV 3.6.2 (Linux), I load the VisIt plugin. -I open two 3D IJK ordered Tecplot files (*.tp). No problem (PV freezes while loading the files, but I can continue after the files are loaded). -I extract the J=1 surface for each file, I group the two extracted surface and I color this new dataset with one variable. -I save the state of my work in a *.pvsm file. -I disconnect to clear all data. -I try to load the saved pvsm file. PV freezes as it does while opening Tecplot files, then it crashes! The same crash happens when I try to load the state file after restarting PV and reloading the VisIt plugin. Has anyone an idea?

[Paraview] Info about installing ParaView 3.6.2 on RedHat Enterprise
Hi, we installed ParaView 3.6.2 only on Linux Debian and, as explained here http://paraview.org/Wiki/ParaView:Build_And_Install#Build_ParaView, we installed the additional .deb packages required (mpi, qt4, python...). But if we would install ParaView 3.6.2 on Linux RedHat Enterprise, should we install any .rpm additional packages?

[Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files
Hello. I have made an additional test: grouping all tecplot files in a same dataset before any other operation allows to use the saved state file. Test 1: the simple pipeline that cannot be used as saved state: - open Tecplot File 1 | extract subset 1 - open Tecplot File 2 | extract subset 2 - group subset 1 and subset 2 in new dataset 1 - coloring the dataset 1 Saving state of this pipeline, loading the pvsm file crashes PV. Test 2: the more complex pipeline that can be used as a saved state: - Open Tecplot File 1 - Open Tecplot File 2 - group loaded Tecplot Files 1 and 2 in new dataset 1 | extract block 1 from dataset 1 (content of Tecplot file 1) extract subset 1 from bloc 1 | extract block 2 from dataset 1 (content of Tecplot file 2) extract subset 2 from block 2 - group subset 1 and subset 2 in dataset 2 - coloring the dataset 2 Saving state of this pipeline, the pvsm file can be used. Note: After loading the pvsm file, you must go on the reader of each tecplot file, select the arrays (unselected by default), then click apply. Of course, I can attach the two corresponding pvsm files if it may help.

Re: [Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files
Hi Dave. I attached a tar gzipped file that contains the two pvsm files: essaipv01.pvsm : state file of Test 1, crashes PV. essaipv02.pvsm : state file of Test 2, OK. I can't send my two formatted Tecplot files (too big) but I think you can easily rebuild them with any data from the headers below. Each file is a formatted Tecplot file with name ending with .tp There is only one zone (block) per file. Each zone is a 3D IJK ordered grid with coordinates x,y,z and some other scalar arrays (pressure, temperature, etc...) Following are the file headers where you will find the dimensions of the grids and the variables: - File 1: TITLE = E_Fld0001_RAPRO2_F06_M020 VARIABLES = x y z vx vy vz M p Pi rok viscrapp ro tsta tgen ZONE T=Window(s) : Dom0001, I=181, J=9, K=97, F=BLOCK -File 2: TITLE = E_Fld0002_RAPRO2_F06_M020 VARIABLES = x y z vx vy vz M p Pi rok viscrapp ro tsta tgen ZONE T=Window(s) : Dom0002, I=61, J=9, K=25, F=BLOCK Best regards, Richard Dave Partyka wrote: Hi Richard, please do.

Re: [Paraview] How to make movies using trajectory data of granular particles
Hmm. Sounds like there is something wrong with the format of your data or
something is wrong with ParaView's reader or your data file is using some
feature that ParaView's reader does not support. At any rate, there is not
enough information here to diagnose the problem. It would help if you posted
your data. Hopefully someone on the list who knows more about the XYZ
molecular data format can look into it. (I have never used it.)

[Paraview] Peavip enables VTK filters and sources in ParaView
Dear all, I launched a few months ago an initiative on github. This is called Peavip and aims at exposing VTK filters to the ParaView GUI. The structure is as follow: - each filter/source has its own XML description (ServerManagerConfiguration) It allows for fast loading of particular filter, without having to build something - a CMakeLists gathers the XMLs in order to produce a cxx plugin The user can load all XMLized filters thanks to a single so/dll/dyn file. This git repository is under development, and new features wil be added, I hope, soon. Coming next: - Choice of exposed filters during the CMake setup - Documentation!! - Categorization of filters in the Filters menu from ParaView - ... ideas from the community You will find the Peavip git repository here: http://github.com/jeromevelut/Peavip Although this is a pre-alpha-Proof-of-concept-preliminar software, I hope that it will be useful for people. Feel free to send feedbacks!

Re: [Paraview] Git repository (mirror)
Thanks. ssh wont work for me and using the proxy git fails at the same large file than before. Regards BastiL Am 21.01.2010 22:13, schrieb Moreland, Kenneth: I believe there is a bug in git that causes the http transfer to fail when dealing with files above a certain size, and the ParaView repository has at least one such file. That said, I also am behind a firewall and I have found (well, been told) two methods that have worked for me. The first (and better but harder) solution is to set up a proxy for the git protocol. To do this, first set up a script that tunnels connections through an HTTP proxy. Copy the following into a file called git-proxy.sh. #!/bin/bash ( echo CONNECT $1:$2 HTTP/1.0; echo; cat ) | nc /proxy-host/ /proxy-port/ | ( read a; read a; cat ) You will of course replace /proxy-host/ and /proxy-port/ with the host and port of your http proxy. Also keep in mind that this script is supposed to be exactly two lines (regardless of whether it has been broken up by an email program). Once you have this script, you then tell git to use it as the proxy for the git protocol. Execute this script once and it will put the necessary parameter in the global git configuration for your machine. git config --global core.gitproxy /path-to//git-proxy.sh I have gotten this to work on Mac and Linux. I have not tried this on Windows. If you cannot get that to work, another method you can try is to get the data from github.com via ssh, which I presume your firewall will let through. To do this, do the following. 1. Create an account on github.com if you do not already have one. 2. Go to Account Settings - Account Overview - SSH Public Keys and add the public ssh key for your machine. 3. Go to the Kitware/ParaView repository on the github.com web site. 4. Click on the button to *fork* the repository. This will create a clone of the repository under your account. 5. In your clone of the ParaView repository, you will see that there are more URL's available to download the repository via git. Choose the *private* URL. It will have the form g...@github.com:yourname/ParaView.git. Although it looks like the regular git protocol, it is not. It is different. Underneath it uses the ssh protocol (I think). 6. Anyway, paste that URL to a git clone command on your local machine. As long as your ssh keys are set up correctly, you should be able to retrieve the repository. 7. Once you have a clone, you can create a new remote that points back to the original Kitware/ParaView repository. At this point you should be able to pull updates directly from the Kitware/ParaView repository through the http protocol so long as no one adds a large file. Hope that helps. -Ken On 1/21/10 12:51 PM, bastil2...@yahoo.de bastil2...@yahoo.de wrote: I am wondering if I am the only guy that has problems with the htt checkot of this?

Re: [Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files
Hi Richard and Dave, I think that the way the VisIt plugin currently communicates information between client and server is not going to work with state. The way it is now the plugin repeatedly sends variable length vectors of array,block,material ids,, etc one array for each mesh. Each of these might have a different size depending on the user's selections. In order to work around the fact that PV sm vector props don't support variable length vectors it also expects the array of mesh ids to be sent first, from this it sizes the other arrays to fit what will be incoming. One solution would be to serialize the users selections in a single string, using sm string vector property to send server side. That would work with state. Otherwise I'm afraid your going to have to do some heavy sm programming. I regret the way I did that, if it's helpful I'll volunteer to fix it. Burlen Dave Partyka wrote: Hi Richard, please do.

Re: [Paraview] Application using Paraview library in C++
Hi,
You should include the exact error message you are getting so that people
can help.
I'm not very familiar with building custom apps using paraview so I won't be
able to answer your question exactly... but to change the representation to
volume you must create proxy objects for a lookup table and a piecewise
function, then assign them to the representation's proxy properties
LookupTable and ScalarOpacityFunction.
The best example I have is in python- a image-data source is created and the
representation is set to volume, the scalar value 37 is set to the color red
with an opacity value of 0, and scalar value 270 is set to the color blue
with opacity value 0.5:
Wavelet()
rep = Show()
rep.ColorArrayName = RTData
rep.Representation = Volume
lut = CreateLookupTable()
lut.RGBPoints = [37, 1, 0, 0, 270, 0, 0, 1]
rep.LookupTable = lut
func = CreatePiecewiseFunction()
func.Points = [37, 0, 270, 0.5]
rep.ScalarOpacityFunction = func
Render()
Goodluck!
