Hi all,
How do i calculate viscosity from the damping factor in fix langevin?
What is the relation between viscosity(force/velocity) and damping factor(time)?

Hi all,

please see the fix langevin documentation, where it says:
Ff is a frictional drag or viscous damping term proportional to the particle’s velocity. The proportionality constant for each atom is computed as m/damp, where m is the mass of the particle and damp is the damping factor specified by the user.

Thank you.
