[lammps-users] Solution for ERROR on proc 0


While running simulation I am receiving the following error after few timesteps.

“ERROR on proc 0: Failed to allocate -1918569276 bytes for array neigh:binhead”

Which causing this error? How to solve this error? I am using LJ potential; neighbor 0.5 bin. Please help me in this regards.

Thanks and regards

How big is your simulation box when this occurs?
If you're using shrink-wrapped boundary conditions
and have blown atoms far out of the simulation
box, then this can happen. I.e. you are trying to
bin up a galactic-scale domain.
