PETSC ERROR

[am2021-create]

Hello everyone

May you kindly assist me, I am using Ubuntu 18.0 . After installation of PETSC, it prompted the installation successful. Now when run the rheomultiRegion tutorials they run successfully but when I change input files in one of the tutorials according to the problem I am working on I get the below error :

[0]PETSC ERROR: #1 User provided function() line 0 in unknown file

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 50152059.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

I am not sure on how to resolve this issue, may you kindly assist with guidance on how to resolve this .

Thanks

The FPE is related with the change you did. There is a division by 0 and one million reasons could be behind it, depending on what you have done.
