I use LAMMPS minimize command for minimising my binary system (50:50 mixture) of LJ particles. The command I use is
minimize 1.0e-4 1.0e-6 1000 1000
When I take the minimized configuration from LAMMPS and minimize it again using my self written code, I find that the system minimizes itself again. I tried to change the etol, ftol etc and did the same steps but found that the system again goes for minimisation. Could anyone tell me what can be the reason for this?
