Hi Hess,
Thanks for your comments, although we have difference in this
topic. The carrier of depletion force at least for me is
not sure. So we want to do a test anyway in this way.

I don't understand what you mean with the second sentence.

But with respect to the first one, in most cases it does not make much
sense to have small solvent particles around a big coarse-grained
since there will be no specific interactions between the solvent and the
solvent particle.
One can therefore just as well use large solvent particles and speed
up the simulation.
