GROMACS version: 2021.3
GROMACS modification: No
There are n molecules of type SOL in a certain GRO file. These n molecules are randomly distributed in the box.
I want to apply a constant force on all molecules of the same type, I am following this but it requires setting an index or so, and appears to be too complicated.
I just want it as simple as:
pull-name = SOL
then it pulls the Center of Mass of all the SOL molecules
How to achieve this?
