Hi,

I included the MEAM package when I built my
copy of LAMMPS in ubuntu

I want to use modified EAM potential.I used the following commands in the simulation.

 pair_style MEAM
 pair_coeff * *  SiC.meam  Si C
 but it's showing the  ERROR: Invalid pair style

 How can i fix this error?

Than you

LAMMPS scripts are case sensitive.

pair_style MEAM

is wrong, because it’s different from

pair_style meam

Hi khannan,

Did you build your lammps executable with the MEAM package and library included? I suspect that the problem is not in your input file but in your (standard-built?) executable. Please see the manual section on how to include optional packages like MEAM when compiling your executable.

greets,
Peter
