There is no such thing as "out of the box". You are looking at an arbitary visual representation of the system. http://www.gromacs.org/Documentation/Terminology/Periodic_Boundary_Conditions https://twitter.com/dr_dbw/status/909559339366572032 Catch ya, Dr. Dallas Warren Drug Delivery, Disposit

It likely in nvt you used constraint so your structure is not so much different from initial, In NPT you removed constraint. When you visualize or analyze result, you need remove boundary condition as Justin said above On Tue, May 15, 2018, 07:43 Dhumal, Nilesh wrote: > Hello Users, > > > I am r

Hi Dr. Warren, You're right - the water does fill up the entire space when neighboring images are turned on. By reading online, I learned that it is okay if molecules seem to move away from the box during the simulation and the visualization can be fixed through the use of 'trjconv', but is it ok
