Dear users,

How can I restrain a certain atoms on a plane?
For example, I want to restrain phosphurus atoms of lipid molecules at z=1.0 nm.
Is there a way to do this?

You can either freeze in one dimension or position restrain to a plane, by setting the force constants appropriately. In that case the atom will go out of the plane however.
