hi,all
I try to use eam/alloy potential,part of the input is
units metal
boundary p p p
atom_style atomic
lattice fcc 3.52
region box block 0 16.0 0 10.0 0 2.828427
create_box 3 box
lattice fcc 3.52 orient x 1 0 0 orient y 0 1 1 orient z 0 -1 1 &
origin 0.5 0 0
create_atoms 1
pair_style eam/alloy
pair_coeff * * coal_kist.eam.alloy Co Al
The output shown the error:
Lattice spacing in x,y,z = 3.52 3.52 3.52
Created box = (0 0 0) to (56.32 35.2 9.95606)
1 by 1 by 1 processor grid
Lattice spacing in x,y,z = 3.52 4.97803 4.97803
Created 1856 atoms
ERROR: Incorrect args for pair coefficients
what pair_coeff form shall I follow ?
Thank you a lot.
