The Langevin thermostat and Langevin dynamics are really one in the
same, assuming you aren't talking about overdamped Langevin dynamics.
You can use generalized Born implicit solvent
( coupled
with "langevin on"

I've used the "langevinFile" option to set different friction
coefficients for different particles. This means that you can set the
diffusion coefficient (in the long time limit) for your particles (or
