Hello everybody,
the 30 october version of the User Manual warns that the meaning of the gamma parameter for the Langevin thermostat has been changed from a relaxation time, as it used to be, to a friction coefficient.
Can anybody tell me what is the conversion formula from old to new parameters?
Reading the paragraph, I guess the mass's particle is involved; but what if I have two types of particles with different masses?
Thanks, best
Paul
