[lammps-users] Tdamp and T-coupling

Hello everyone,

In fix NVT and NPT command, there is a parameter named Tdamp, which is specified intime units and determines how rapidly the temperature is relaxed . We can read a parameter T-coupling in article, for example, Nosé–Hoover coupling constant is set to 5.

I am confused by the two parameter. What is the difference between them, and the relation of them. Could some kind people give me some suggestion?

Thanks in advance.

Tdamp is the coupling constant - i.e. the "mass" of the thermal
piston being coupled to.
