Dear users,

I am stuck in using meam potential.

As I understand the usage, I put meam arguments like this,

`pair_coeff * * library.meam Ni V NiV.meam Ni V`

asterisks to span all types of atoms, exporting elements, parameters, and the target types with names.

But I kept getting incorrect args error in this line.

Can you give any advices ??

Thank you!!
