[Paraview] ParaView 4.4 ??
Dear all, I just came across this interesting webpage: http://www.paraview.org/ParaView/index.php/ParaView_4.4_Deliverables and I would like to know if there is a release schedule for ParaView 4.4.

Re: [Paraview] Issue with structured grids and extraction of boundaries with cell data
Hello,
my previous mail was wrong. The present problem is not related to those
other bugs.
Here, when using ExtractSubset the extent for cell data in miscalculated
if i==imax or j==jmax or k == kmax.
in vtkExtractGrid.cxx: we have the call
this-Internal-CopyCellData(inExt,outExt,cd,outCD); that use point extent
and then in vtkExtractStructuredGridHelper.cxx the extent is computed
for cells
vtkStructuredData::GetCellExtentFromPointExtent(outExt,outCellExt);
but this later function does not know about the whole extent of cell
data. Thus you need to pass down a valid extent for cells before calling it.
If you have inExt = {0, 30, 0, 20, 0, 10} and you pass outExt =
{0,30,0,20, 10,10} the result outCellExt will be {0,29,0,19,*10,10*} and
then the copy of cell data will be done outside of the array leading to
segfault.
The outExt extent should have been corrected to be {0,30,0,20,9,10} or
{0,30,0,20,9,9}...
I hope it is clearer now.
Best Regards
Mickael

Hello,
I'm working with a 3D structured dataset containing cell data. I tried
to extract a 2D boundary of this dataset corresponding to the maximum
index of a dimension with the Extract Subset filter and ParaView 4.3.1,
and I found an issue: the resulting dataset is incorrect. It holds cell
data from the opposite boundary (eg. if I try to extract the i = imax
boundary, I get values from i = 0 boundary), and these values are
shifted of one index in the other dimensions.
This case worked with ParaView 4.1.0, maybe it is related to this other
bug about structured data :
http://markmail.org/message/fvatgidqbvnufgi6#query:+page:1+mid:fvatgidqbvnufgi6+state:results
?
Here are some pictures showing the problem on a simple dataset which can
be used to reproduce it:
- The simple .vts file : http://z1.gb2n.org/pv/test.vts
- The original dataset : http://z1.gb2n.org/pv/original_dataset.png

boundary : http://z1.gb2n.org/pv/extract_subset.png

Re: [Paraview] Issue with structured grids and extraction of boundaries with cell data
Hello, I managed to reproduce the problem. The difference between ParaView 4.3.1 and previous version comes to the removal of vtkPVTrivialExtentTranslator in the pipeline. Thus, the update extent requested by the extract filter may not be updated correctly anymore. It is a similar problem to this other bug: http://marc.info/?l=paraviewm=142168609529307w=2 Best Regards Mickael On 20/03/2015 16:26, Etienne Tang wrote: Hello, I'm working with a 3D structured dataset containing cell data.

Re: [Paraview] Fwd: Gradient of Unstructed dataset
Hello, sorry to intrude, I think the problem may come from the CGNS loader of ParaView. When using the CGNS plugin from ParaView development version, you get the same picture as Ensight. My two cents Mickael On 17/03/2015 05:04, Masaaki SHOJIMA wrote: Hi Berk, I appreciate your kindness Here, I attaches the data. Compare Gradient.pdf (252KB) A calculated field by SC/Tetra solver is uploaded in Dropbox. (Calc.zip) Please download the data. It contains FLD format for SC/Tetra post and CGNS format for Ensight and Paraview. https://www.dropbox.com/s/5fpeu1qwhyzjn5u/Calc.zip?dl=0 (1) I calculated the flow and the pressure in a simple cylinder for a test ( diameter 0.005m, length 0.01m). Plug flow at inlet with 0.03 m/s. (2) Data were transfered to Ensight and Paraview in CGNS format. (3) Pressure was mapped on the surface and compared between SC/Tetra post, Ensight and Paraview. All application provided same results. (4) Gradient (pressure) was calculated in each post and z-component of Gradient (pressure) was visualized with same colored contour. Only paraview provided a different image because the computed gradients in paraview had half values compared to SC/Tetra post and Ensight. (5) Gradient (velocity-X) was also calculated in each post and the X-component of Grad (velocity-X) was visualized. Same results as shown in 4. Thanks a lot.

Re: [Paraview] cgns - Paraview loader
The CGNS plugin is not present in nighty builds. You may have an unrelated problem. Have you check your cgns file with the /cgnscheck/ utility ? Can you provide more information about the error output from ParaView ?

Re: [Paraview] Performance of the CGNS Reader
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.

I am testing the CGNS reader of Paraview 4.0.1 64 bits running on a Linux Workstation having 4 CPUs and 5.8 Gbytes of memory. Paraview was installed from the binaries available on the download page. I am trying to load a 1.36 Gbytes CGNS file that is available through the network. While loading this file, the Paraview Windows is frozen and cannot be refreshed, and I must check with the ps command on a terminal window or with a system monitor if PV is still running or if it is really frozen. A progress bar for all readers would be welcome in a next release. Finally, the file can be loaded, but it always takes about 15 mn (+ or - 1 mn depending of the load of the network), while Tecplot always loads the same file within less that 1 mn ! How do you explain this poor performance of the CGNS reader ? Can it be improved, or am I missing something ? Is there some Paraview option that could reduce loading time of large files ?

[Paraview] GL2PSExporter and python
Hello,
I am testing GL2PSExporter in paraview 3.98 from python shell.
Thus, I do:
exporters = servermanager.createModule('exporters')
svgExport = exporters.GL2PSExporterSVG()
svgExport.SetRenderWindow( view1 )
svgExport.FileName = /home/mickael/test.svg
svgExport.Write()
Unfortunately, it crashes paraview.
It seems that SetRenderWindow and Write methods are not available in python.
Did I do something wrong or is it a bug in python wrapping ??

Mickael PHILIT
