Hello Rahul,

i simulated my model without UDF in parallel again yesterday. The simulation run 16 hours on an HPC, and it schowed following error message:

==============================================================================

Node 7: Process 27237: Received signal SIGSEGV.

==============================================================================

I guess the error Received signal SIGSEGV is not from UDF but from mpi. mpi cannot process data in time. i don't know if my guess is correct. Do you know how to solve this problem?

Best Regards,
