[gmx-users] How to calculate lateral pressure for monolayer compression or expansion

Dear Users,

As I want to simulate surfactant monolayer with different molecular area in
order to reproduce the LB experiment (isotherm plot). So I have to fix a
number of surfactant molecules but only surface area is changed by applying
the lateral pressure. However, I don't know how to calculate the lateral
pressure for the monolayer compression or expansion. Could anyone please
suggest me how to do this?


Thank you
