Hi, I did try to determine the differences between the ParaView built in reader and the one supplied by OpenFOAM, but could not find any documentation on this. I do know that the ParaView built in one has been improved in recent releases and seems to do all that I require of it. I tend to use RHEL6 systems and I believe that the OpenFOAM only support an older version of ParaView on these systems, so I rarely use paraFOAM. I tend to use ParaView 4.4 but have not done any timings with it yet. There is also a version of 4.4 with the OpenGL 2 backend that may be faster. Ron

I also didn't realize that Paraview had a native OpenFoam reader. What functionality (normally supplied by OpenFOAM paraFoam ) is lost when using Paraview without starting with paraFoam? I'm asking because I've heard that ParaView 4.4 is extremely fast and would like to test it out with OpenFoam files but not paraFoam.

Then point ParaView at that file and it will use the builtin openFoam reader which should offer the reconstructed/decomposed option. The empty file just tells ParaView which reader to use based on the extension.

I found a web page that shows the "case type" chooser. They were opening a .foam file. I have .OpenFOAM case. Should I consider converting the foam to VTK?

Look on the properties panel when you open the file and before you hit "Apply" look for a chooser for "Case Type". The default is "Reconstructed Case" so change it to "Decomposed Case".

I have a 48 core machine. I have correctly installed and compiled a parallel copy of paraview 4.1.0 with OpenFOAM 2.4.x. If I open a simple .obj file I can see that different parts of the surface are rendered using different processors. I can also see that the memory is shared among the parallel processes. When I open a reconstructed openFOAM solution with 20 million cells with paraview connected to 40 process pvserver, the image seems to be rendered (or processed) with only 1 processor. Is there a step that I'm missing to parallelize the reconstructed Openfoam data files for rendering? -- Leonard Cassady PhD Senior Development Engineer Intuitive Machines Cell: 281-755-2553<tel:281-755-2553><tel:281-755-2553<tel:281-755-2553>> _______________________________________________ Powered by www.kitware.com<http://www.kitware.com><http://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 Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview -- Leonard Cassady PhD Senior Development Engineer Intuitive Machines Cell: 281-755-2553<tel:281-755-2553><tel:281-755-2553<tel:281-755-2553>> -- Leonard Cassady PhD Senior Development Engineer Intuitive Machines Cell: 281-755-2553<tel:281-755-2553> -- Leonard Cassady PhD Senior Development Engineer Intuitive Machines Cell: 281-755-2553
