ERROR on proc 0: Incorrect element names in EAM potential file (src/MANYBODY/pair_eam_alloy.cpp:132)
Last command: pair_coeff * * GaAs.bop.eam.alloy Ga As GaAl.bop.table (381.0 KB)
I want to get eam file between aluminum and gallium. But I can’t get eam file even though I use method in lammps manual. Please tell me how to get eam file without using openkim. Thank you.
I don’t see any EAM potential for GaAs in the OpenKIM database, just the two potentials (BOP and Tersoff) that are also in the NIST database.
You either find potentials in the the various databases, the published literature, or you have to parameterize them yourself or find somebody knowledgeable that can do this for you. Potential parameterization is a non-trivial task to get it properly. You you saying “I want it” is not going to have much of an effect.
Besides, do you think that an EAM potential is a good choice to represent a material like GaAs?
I don’t.
You can start right away by editing your “messy” original post and resolving the inconsistencies in them with the attached file.
