[lammps-users] npt box length changing independly

Thanks for your response.

But during my caluculating of ellipse, I found the Tdamp parameter is somewhat out of use when I set the Pdamp smaller than 5000. If the Pdamp = 100, the system temperature will increase continuously and then the system break.

Whether the pressure adjusting takes precedence of temperature adjusting? What is the origination of the phenomena?
