Dear All,
I use lamps to study the friction behavior between polymers, and want to hold the temperature of thermostat part of the system at a constant value. I am wondering how to set the damp factor in fix langevin command. If the damp factor is large, the temperature will go up after a long time friction, but if the damp factor is small, the temperature will oscillate greatly around the set value. Could you give me some advice on the damp factor setting?
Thanks in advance,
Fangli
