Hi everybody,

I got a problem with reconstructing my fields after running "interDyMFoam" with "dynamicRefineFvMesh" in parallel.

A first thing to say is that I am sure the simulation completed successfully, because I can postprocess the results for each processor alone.

The reconstruction of the mesh using "reconstructParMesh" still works fine, although I think I did not use the easiest way, as I have to use "reconstructParMesh -time x.xx" for every single timestep.

My problem occurs when doing "reconstructPar" to reconstruct the fields. When I am trying it from inside a case directory, the function aborts already during the first timestep. I found a tip in another thread that it might help to use it like "reconstructPar -case xxxxx" from outside the case directory. I was kind of surprised that it almost worked this way. But still, after about the half of the timesteps, the function aborts, always showing the same error:

Speicherzugriffsfehler

I do not know why the last line is written in german, but I think it can be translated as memory access error (Do not know if its exactly called like this in english).

Has anybody got an idea how to solve this problem? I also tried running the case on a single processor and this worked absolutely fine, but for those cases I want to use it a single processor will work for weeks, so that is no option.

Thanks a lot for your help!

Greetings Sebastian
