Dear gmx-users:

I am still learning how to use GROMACS  and i would appreciate if someone could
help me with this message error in Molecular Dynamics:

Error on node 2, will try to stop all the nodes
Halting parallel program mdrun on CPU 2 out of 6
-------------------------------------------------------
Program mdrun, VERSION 3.3
Source code file: nsgrid.c, line: 220
Fatal error:
Number of grid cells is zero. Probably the system and box collapsed.


I don’t know what this means, does anyone know?
Thanks in advance!
Amanda
