NPT , Tdamp-Pdamp

Dear LAMMPS users ,

I have a big system and I use lj units .

​the time step is : 0.0005
this is my npt command :

fix 1 all npt temp 2.15 2.15 0.1 iso 20 20 1.0

​Is Tdamp and Pdamp acceptable for my system ?
Do you have any other suggestion ?

Thanks for your attention.​

The fix npt doc page provided some rules of thumb to choose the dampings.


I was wondering what a BIG system is.
What is the unit style your are using?
You may check the doc for some explanations and hints.
