[OpenFOAM] Parallel Rendering of openFOAM with pvserver

im_lenny · September 30, 2015, 15:13

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.

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?

The paraview reader for OpenFOAM data is not written for distributed processing. That is why native OpenFOAM files can't be visualized in parallel with pvserver.

Does anyone know the most efficient (time and storage) method for post-processing large OpenFOAM solutions? I have a time series of 6 second length recorded at 200 Hz with 20M cells.
