I have a question about “boundary” command.
I would like to apply PBC only to X and Y directions.
When I set 'boundary p p f ’ or ‘boundary p p p’, it works well for my simulation system where I put something in a vacuum box.
But If I change it to “boundary p p s”, The process is killed with information that
" Rank 0, Process 22491 received signal SIGSEGV(11)
MPI: --------stack traceback-------
Why? Besides, can someone explain the difference between “f” and “s” in this command. I am not clear about the instruction in MANUAL.Thanks.
Happy new year to you guys.
