FeCr potential

To whom it may concern,

I am trying to use the FeCr potential given in lammps-14May16. I am getting an error [ERROR: Incorrect args for pair coefficients (../pair_eam_alloy.cpp:52)]. I know my previous code is wrong but I cannot figure out what is wrong. This is my code.

dimension 3
boundary p p p
lattice fcc 40 orient x 1 0 0 orient y 0 1 0 orient z 0 0 1
region box block 0 4 0 4 0 4
create_box 2 box
create_atoms 1 box
pair_style eam/cd
pair_coeff * * ../potentials/FeCr.cdeam
timestep ${dt}
thermo $d

Thank you for your time and help.

Please check this page : http://lammps.sandia.gov/doc/pair_eam.html

Your pair_coeff has to be : pair_coeff * * …/potentials/FeCr.cdeam Fe Cr
