[gmx-users] Reducing fast motion with Langevin Dynamics

[Bob Johnson]

Hello everyone,
I am simulating the adsorption of single stranded DNA on a carbon nanotube under
aqueous conditions. I would like to reduce the fast motions in my system so that
I can increase my timestep. Is there a way to do this with Langevin Dynamics? I
would like to keep explicit solvent so I would have no use for the random force
that is included in Langevin Dynamics. All I would like is to have a friction
term that reduces fast motion in my system.
Thanks,
Bob Johnson
