Hi everyone,

I have a question about setting the atom mass.

in the input data file I use Mass command give
the atom mass. But for some reason the value in
the data file is not correct.

in LAMMPS script I read in a EAM potential file
after read_data command. I want to know if the
mass value in the EAM file will overwrite the one
given in the data file?

thank you.
