eam for individual parameters in a mixture

Thanks, now i have both potentials taken of the same reference. But i modify the input file, just to read only one compound the palladium(this for answer your question"do they work for the individual pure systems?"), but in this case the failure is different, he show me (Invalid mass value (…/atom.cpp:1041)) i don’t can understand what happened, thanks.

here i show you the data file for a individual pure system

2 atoms
1 atom types

and the first line of .eam file of the palladium

and here a piece of input file for a individual pure system

that hints at the potential file not being formatted in the way that
eam pair style expects. due to the ad hoc nature of such files, it is
up to the user to make sure that potential files confirm to the
program's expectations. LAMMPS supports reading different popular
variants of EAM potential files, as detailed in the documentation.
difficult to say from remote, what exactly is going on. best you
re-check with the information provided in the LAMMPS documentation and
compare to the details of the description of the files that you
downloaded.
