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

<p class="MsoNormal"> I didn't realize that there are 2 different extensions for OpenFOAM projects. 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. <u></u><u></u></p>

<p class="MsoNormal">Hi,<br>
It is simple to create a .foam file; just do "touch xxx.foam" in the working directory. 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.<br>

I do not have a chooser for "case type". I found a web page that shows the "case type" chooser. They were opening a .foam file. I have .OpenFOAM case.<br>
<br>
Should I consider converting the foam to VTK?<br>

Looping the list back in to the thread.<br>
<br>
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".<br>

As I recall, reconstructed means that the root node does all the work. Switch to decomposed type in the reader and let us know how it works then.<br>

I'm attempting to use pvserver to accelerate the post-processing of my openfoam solution. 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.<br>
<br>
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?<br>
