Are random forces applied at each step or at a fixed time interval (for
example every 1 ps) when using the langevin thermostat?
The reason for this question is as follows:
If I run a simulation with 0.1, 1 or 10 fs time-step, then the random
forces would be applied 10000 1000 or 100 times during one ps of
simulation. This might mean that the dynamics of the system (strongly?)
depends on the time-step, which intuitively should not be the case.
Thank you & best regards,
