How to postProcess decomposed (parallel run) data

saugatshr4 · May 27, 2022, 04:32

Dear Formers,

I have run my simulation in 16 cores. Now, I want to use to the probe function to extract the data of select points in the domain.

I could do 'reconstructPara' and then use it but the reconstructPara takes a lot of time.

Is it possible to extract the data directly from the decomposed file file format? I tried using the postProcess command, but its not working.

Can you please help me.

Thank You in Advance

I think here you will find the answer to your question.
parallel processing time+reconstruct time<serial processing?!

Can usually use "mpirun -np N solver -postprocces -parallel" without problems where "solver" is simpleFoam, pimpleFoam etc (whatever you used for the simulation)
