Hello Yvan,

Thank you for your analysis, I understand that you can't help more precisely without a more detailed debugging. And I don't exclude some simple stupid error from my side...
Anyway, I tried to uncheck the "use unmodified checkpoint...", but no improvement.
And yes, I double checked several times, the .csm file exists and seems ok, it makes 3GB.

The mesh makes 14M cells, it will be difficult to share it with you.
I attempted running CS with Valgrind: I attach the output, franckly speaking I don't have the knowledge to understand what's inside... Maybe it can help?

Thank you very much for your help and your time.
Best regards,
Daniele

Hello,

To run Valgrind, you need to run it on the cs_solver executable. There are instructions in the user guide for this, but it generally does not work well (or needs additional settings to avoid false positives) on a cluster with a fast network, and with a large mesh, it will be difficult to use in any case.

So the remaining option would be to attach a debugger. I can provide some instructions, or maybe this can be taken offline in a separate discussion (I believe you have my contact info).

Best regards,

Yvan
