I'm postprocessing big data in
 
I'm postprocessing big data in parallel with postChannel utility. I noticed that postChannel does not work in parallel and breaks with the following error. I tried to run postChannel on tutorial case Channel395 and it gave the same error. My guess is that the code responsible for collapsing the field does not work in parallel since it needs to communicate with other processors to do the collapsing. I tried to force the code to collapse the fields at the end, and it only broke at the end, which means averaging works well in parallel. Can any body help solving this problem?

here is the error message:

Also nAveragingSteps.raw is not copied by reconstructPar to the reconstructed folder and has to be copied manually. This refers to V 1.2.

I had the similar problem to run postChannel in parallel as my mesh is very fine with huge mesh points. Does any body how the postChannel will work in parallel or within simulation run?

I would appreciate any suggestions.

Thanks
