I worked on a client and connect with the server(24 cores) by freeNX, I can perform the simulation parallel with openfoam and I can post-process the result with single core by paraview, but I think it is a little slow once I check the result. I want to parallel run the result with paraview. I don't know how to configure the server and client? first I am testing on a single computer with multiple cores? but all failed. can you give me any guidance?

Hi

the OpenFOAM reader is, as far as I know, not parallel. However, you could use the paraview native server and a mpirun. I never tried but it would look like this:

touch case.foam

mpirun -np CPUs pvserver -parallel

Touch the case with the Foam reader or every processor of a decomposed case with the OpenFOAM reader.

Greetings to all!

To add to Fabian's answer, I'll quote myself from another thread:

This feature allows you to not have to run manually pvserver with mpirun, since ParaView will do this for you.

Nonetheless, keep in mind that using multi-core does not always equate to faster performance.

Best regards,
