Dear lammps users,

i am trying minimize a domain with defect,using Fe_mm.eam potential file.i am getting a error message as ‘failed to allocate %d bytes for array pair frho’.
befor this i done the minimization of same domain with potentials files of Ni and Cu.
I have an empty space of 3GB in the sys/folder in which it is running.
in the domain only 2280 atoms are there.

I am unable to find where it is going wrong.
please help me.

How many bytes does LAMMPS say it failed to allocate. If it
is small and your system is also small, then something is wrong
on your system, b/c LAMMPS is not able to allocate a small
amount of memory at startup. Are you using MPI? If so, which one?

Sometimes
MPI will take all the memory and (due to a bug) fail to give
it back to the application.
