[gmx-users] simulating ligands attached to a surface...?

[Daniel Rigden]

Hi all

Can anyone tell me if it's straightforward, or even possible to simulate
ligands that are attached to a surface?  The ligands are permanently
attached but may 'skate' around the two-dimensional surface.  I was
imagining that the atoms through which the ligands are attached could be
constrained in z while being free to explore x and y.  All the other
atoms would explore x, y and z as normal.  Is that possible in Gromacs?

Thanks very much for any advice

Daniel
