Hello @Dieginho and any other participants who have the mesh issue,
I just got some information from our Product Engineer. It seems to be a bug between OpenFOAM and one of the 3rd party libraries, which happens during parallel computing. The issue is still not solved since the reason is non-deterministic at the moment. But we have a workaround for now - if it is necessary to run the mesh at 32 cores please tweak the settings a little bit (say change the bounding box dimension by a very small value or the number of cells along any direction by a very small number, say 1) and re-run the case.
A better solution would be to run it in reduced cores, say 16. This should help for the time being. Meanwhile we are working on it to eliminate this problem completely.
