[gmx-users] Free energy calculation of a charged system

2014-03-14 Thread Valentina
Hello, I need an advise on how it is better to approach the ThermoD integration of such system: +vely charged inorganic layer, filled with water and counterbalanced by -ve organics Do I integrate out organics both VdW and Coulomb, making the system have total +ve charge at lambda = 1 OR: Do I

Hi Valentina - Honestly, I did not get the considerations with charges. TI probably scales interaction energies between selected groups, not charges. Science-wise, I would first decouple organic particle, then decouple chloride anions, and place a right sign between these two free energies. If
