[Lammps Users request] Help about msd

Hi Steve Plimpton
          Thanks you,

I want to know if the sentence in te in.dyn file

variable v0 equal v_0
variable pre equal "$(190*(1.3806503e-23)*773)/(3*v0))" #190 No O2-

computes the initial volumen and pressure in each timestep or only these values are
the initial values? I do not beleive that. because in the MSD plot I saw some Steps
likes:

        >
msd | _____
        > _____/
        > ______/
        >/_______________________
                  time

How I can fis it?

Your MSD plot diagram looks normal, i.e. monotonically increasing
MSD over time. Your variable Q can be answered by reading
the variable doc page where it discusses Immediate Eval of Variables.
