How to fix Erros:"Domain too large" and "segmentation Fault"

LAMMPS LAMMPS Mailing List Mirror

My simulation(similar to couette flow example) runs fine for a geometry with length of simulation box in z=7.22(LJ units). But when I try to increase it to 722 i get error:"Domain too large". So from th mailing list I understand something is going wrong with the way i defined my simulation. When I try to alter my region and simulation box dimensions I either end up getting "Domain too large" or "segmentation Fault" error. I am not sure how to fix this.

Any suggestion would be appreciated.

Thank you.

If the error is:
Domain too large for neighbor bins

then that only happens when one of your box dimensions
becomes to large that > 2 billion neighbor bins are required
(in that dimension).

You can safely assume at that point that atoms have blown
out of your simulation box and you are in trouble. With shrink
wrap boundaries, the box will expand to track those atoms.
