[gmx-users] Adding Virtual Site to the Molecule

[Sikandar Mashayak]

Hi

I am thinking of a simulation set up, where I modify a structure/topology of
a molecule under consideration, in which, I want to introduce a dummy
atom/site which will always be located at center of mass of a molecule and
it will only interact with dummy atom of other molecule.

I am not sure how to achieve this, will really appreciate any help in this
regard.

thanks
sikandar
