HI dear
I have two groups of atoms (group1 and group2) in my simulation. The atoms of group2 are surrounded by atoms of group1.
I want to immobilize group2, but group2 should interacts with group1.
For immobilizing the group2, I don’t include group2 in time integration.
With this regard, does group2 interact with group1. If not, what should I do?
