Hi Gromacs Users,

The error:

mpispawn.c:303 Unexpected exit status

Child exited abnormally!
Killing remote processes...DONE

Following is the link which might help:


I think the above error is because of the PME calculations and changing the
grid spacing might work. But I dont know how to change the grid spacing. Do
you have any idea regarding that? Or if you think the error is due to some
other reason let me know.

I am attaching the .mdp file with this email.

Thanks for the help.
