Actually during the simulation none of my organic molecules evaporate. I restraint the heavy atom of organic molecules in order to capture the a maxima (increment) on free energy from gas phase to organic phase. For the same system I also applied impinging method which I put 100 water molecules on

Dear Gozde: There are a few questions: 1. Does your system remain triphasic? You can check quickly one system with VMD or you can do it quantitatively with g_density (separate profiles for all-atoms, water, organic solvent). I see a triphasic system in your image but that doesn't guarantee t

Dear Gromacs users, In order to estimate the free energy profile of water on organic coated-water system I am using Gromacs umbrella option. I put my water molecule far away from the bulk organic+water system and pulled this molecule through the bulk. When I checked the PMF profile I realized that
