Hi all,
Is it the right way to use "plingen_pz" in MPI mode instead using "lingen"?
When I run "plingen_pz" in mpi mode, an error will be occurred.
In the following, you can find the command and the error.
Can anyone explain me the reason please?
Does anyone have any idea to better running the "lingen"?!
Thanks,
Sara
