[gmx-users] position restrain on a curved surface

[Mohsen Ramezanpour]

Dear gromacs users,

I was wondering what would be a good strategy to force atoms to move on an
arbitrary curved surface?

An example could be forcing lipid molecules to freely move on x-y plane
while their z coordinate is fixed. This is easy because curvature is zero
here. How about the curved surface?


Thanks for your comments in advance

Cheers
Mohsen
