The {meam} style is part of the MEAM package. It is only enabled if
|

LAMMPS was built with that package, which also requires the MEAM

library be built and linked with LAMMPS. The {meam/c} style is

provided in the USER-MEAMC package. It is only enabled if LAMMPS was

built with that package. In contrast to the {meam} style, {meam/c}

does not require a separate library to be compiled and it can be

instantiated multiple times in a "hybrid"_pair_hybrid.html pair style.
