Default Sample From Decomposed Case Wo Reconstructing

Hi everyone,

I have a case of a 2D wave flume simulation, that was run with interFoam as decomposed (8 processors) case. (OpenFOAM v1812)

I needed 8 free surface elevation measurements from 8 different lines so I added them as Raw measurements of alpha.water to the functions sections in controlDict. Everything worked great I get my measurements at each time step simultaneously with the simulation but, I need to look a few centimetres before and after of these lines also.

Now I need to re-take those samples but I don't want to reconstruct cases (also I don't have time to reconstruct them neither)

is there any way to get samples from the existing, decomposed model without reconstructing or re-run the whole thing.

Thank you for the answers in advance.

Yep, post processing works with mpi and the -parallel flag. So do something like:

mpirun -np 8 interFoam -postProcess -parallel

and it will just run your function objects on all the times.
