Re: [Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files
Hi Burlen. Thank you for this answer. Working with state files (as we do with layout files with the Tecplot software) is essential when you have big pipelines. Imagine you spend one hour to build a big CFD pipeline... and you have to rebuild it each time you want to analyze new data! Really, it would be helpful if you could fix this problem in a future release. And also, it would be fine if the state file could save what arrays are selected in the Tecplot Reader (no array is selected when loading state, but is it a PV problem or a VisIt problem ?). The work around with the actual release is to use the Group datasets filter to build a new dataset from the Tecplot readers. At least, it works with single zone Tecplot files, but I will make other tests with multi-zone Tecplot files. PS: I discovered another bug. PV crashes when loading state (with work around) referencing Tecplot files if the Tecplot files are not found! Best regards. burlen wrote: 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.

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.

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.

Re: [Paraview] PV 3.6.2 and VisIt Plugin: crash when loading state with Tecplot files
Hi Dave and Burlen Another Test loading state for a Tecplot file that contains two zones works! - Read two zones Tecplot File - Extract Block 1 | Extract subset 1 from Block 1 - Color Subset 1 - Extract Block 2 | Extract subset 2 from Block 2 - Color Subset 2 Another Test loading state for a Tecplot file that contains only one zone crashes PV. - Read single zone Tecplot File - Extract subset - Color Subset A final Test loading state for a Tecplot file that contains only one zone and using Group datasets filter works! - Read single zone Tecplot File - Group datasets - Extract subset - Color Subset So the problem happens only when reading single zone Tecplot files. The work around is always to use the Group datasets filter after reading, even if there is only one file! No problem occurs when reading a multi-zone Tecplot file. Best regards.

[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] 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.

Hi Richard, please do. I will try running your steps with a debug build and see if I can track down the crash. Thanks for tracking this down!

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] 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.
