Re: [gmx-users] Density of pure tetrolic acid does not agree with experimental data

Nathan, The experimental data ideally corresponds to an infinitely long, well-converged MD simulation at the corresponding set of temperature and pressure, not after EM and most certainly not after just filling a box, where spacing is according to a preset cut-off and not due to interatomic

Hi Nathan, Yes, placement of molecules neglects the interactions. You need to simulate the stuff before drawing conclusions. Cheers, Tsjerk On Mar 31, 2015 8:43 AM, Nathan K Houtz nho...@purdue.edu wrote: Hello Gromacs users, I tried to create a 6.5 nm cubic box of tetrolic acid (otherwise
