regarding meam potential

Dear LAMMPS users,

I have a query regarding the MEAM poentials.

The pair potential in the MEAM models is not given explicitly, but is specified in such a way that, when combined with the embedding function, it reproduces the EOS for the reference crystal structure.

In some of the new MEAM potentials, authors have modified some parameters by slightly changing the EOS.

My question is do we need to change the EOS in the source file for the same to apply or just by changing the parameters the EOS changes.

Any help in this regard is highly appreciated.

Impossible to answer in general. You ahve the documentation

for what can be changed in the input potential files.

If that is not sufficient for your needs, you’ll have to modify

the source code.
