Dear all

I have a system consisting of 2 substrates (20 nm distance between them) and inside them there are polymer chains. I would like during my NVT simulations the substrates NOT to move (I suppose I have to put the velocity of the COM of it's substrate to be zero).

Does anyone know how to do that?

The simplest way is to just use position restraints. The positions may change very slightly, but not a noticeable amount.

If you absolutely require no movement at all, use freezegrps in the .mdp file.
