Dear lammps experts,
I created a Cu-bicrystal sample with a Sigma5 boundary and wrote a restart file. While creating the bicrystal, the potential I used was "Cu_mishin1.eam.alloy" and also the number of atom type was specified as 1.
Now, I am trying to segregate 1% of Zr-atoms in the boundary. I want to use new potential "CuZr_mm.eam.fs" and also change the number of atom type to 2.
Could you please suggest me how can I change the potential and number of atom type so that I can start my simulation using the restart file.
