LAMMPS will print the info and immediately exit if this switch is used. compute msd. LAMMPS is a classical molecular dynamics simulation code with a focus on materials modeling. See the read_restart command for info on how to re-specify a fix in an input script that reads a restart file, so that the operation of the fix continues in an uninterrupted fashion. LAMMPS fix : Which fix should I use if I want to study diffusion of a small molecule in a polymer (fix npt nvt nve or something else)?.
