Hi All,
I am trying to move atoms at the boundary with a constant velocity, with fix setforce set to zero for x,y,and z. (for applying a strain rate).
Though my coordinates at the boundary are properly getting updated every timestep, but the box dimension only gets updated at some interval say after 5000 or 10000 time steps depending on the applied velocity. (usually it gets updated when box get extended by 1 angstroms in Z direction (direction of strain).
My question is why the box size is not getting updated every timestep ?
Thank you
