hi everybody
i have a doubt regarding eam potential. If i have EAM potential for an
alloy (say made up of elements A-B) but i want to use only the EAM
potential of one element say A. Is it possible to do in lammps? if so
how can i do that? any help is highly appriciated.

Dear Udayagiri-

It's not a problem... just don't create any atoms of the second type. LAMMPS will only look at the part of the EAM potential file that is relevant to the type you're interested in. You specify in the pair_coeff command which atom types correspond to which elements.
