Dear gromacs users, Sorry for repeating my question. I didn't receive any email so I couldn't reply and I missed them. I am using following pull code in md simulation for pulling a ligand across the plasma membrane model. Ligand passes through the membrane,but along simulation, the size of

Does it do that without using the pull code, i.e. just performing NPT simulation? What is physically happening? Sounds like the bilayer is unstable. What forcefield is this? Catch ya, Dr. Dallas Warren Drug Delivery, Disposition and Dynamics Monash Institute of Pharmaceutical Sciences, Monash

Dear gromacs users, I am using following pull code in md simulation for pulling a ligand across the plasma membrane model. Ligand passes through the membrane,but along simulation, the size of axis z increases. My size box is 8.52807 8.52807 14.0. And the pull distance is less than one-half
