I want to minimize energy for MoS2, but when I try it with NPT ensemble, all the atoms changes its position.
Hello everyone, I am trying to calculate shear-stress vs shear strain in Graphene. I made two group of atoms upper and lower, out of which for upper, I setforce 0, 0, 0 and for lower gave constant...
