[gmx-users] Dispersion Correction using Charmm36 FF and compressibility

2019-01-26 Thread Frederic Schneider
Hello, I have two question regarding the simulation of a solute in different lipid solvent (mixture of triglyceride, which is a simplified version of the complex oil) as well as other solvents like carbitol. I use the parameter from cGenFF together with the charmm36 forcefield. First

Dear gmx users I am trying to simulate my complex using amber99sb ff. There is no amber tutorial in gromacs. I need to know how dispersion correction set in the .mdp files . I can not understand the definitions of DispCorr in mdp option. Should I put it on EnerPres or no ? Would you please

2014-03-28 Thread Jason Grosch
Hello, I'm planning on studying several large protein clusters using the gromos 54A7 force field with the following cutoff parameters: rlist=1.0 nm, rcoulomb=1.0 nm (long range handled by PME), rvdw=1.4 nm, and the short range list will be updated every 10 steps. I am interested in studying
