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:

Create time

Create mesh for time = 120


Reading transportProperties
Collapsing fields for time constant
Collapsing fields for time 40
