[gmx-users] Restrict rotation between 2 molecules

Dear amir: You have 2 issues: 1. maintain planar plates 2. inhibit plate rotation. I think that the planarity is actually going to be a bigger problem for you (unless of course you want your plates to be able to bend). Position restraints in the relevant dimensions seems like a reasonable

[gmx-users] Restrict rotation between 2 molecules

Hi, i want to simulate 2 parallel plates (each composed of single atoms with equal spacing , for example 2X2 atoms plate) i want to simulate them such that they are parallel to each other and can move only along one axis (for that i used posre.itp..) what is the best best way to prevent them from
