​there is not enough information here to give any recommendations. while
this may be triggered by the commands you highlight, this kind of MPI error
usually originates from some *other* command causing stray MPI messages.

you need to report which LAMMPS version you are using and on what platform
you are running and provide a *complete* input deck and the exact command
line, that you are using, so that somebody else can investigate and try to
reproduce the failure you are seeing.

Dear User,

Thank you very much for your suggestions.
The problem I was facing has been fixed after installing newest lammps version.Newest lammps will not face this problem.

Thank you

All Best
