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.
