And which one (and with what parameters) is better for the QM/MM optimization? Steep almost didn't change anything and I couldn't relax the system as I wanted. CG seemed to work fine, but in the end it teared an H-atom from my QM subsystem. BFGS could not work with the constraints which are

Hi, It is possible, but only using gromacs' internal optizers: SD(steep), CG, or BFGS. And you can only optimise minima, not transition states. Best, Gerrit Message: 3 Date: Thu, 1 Mar 2018 12:44:53 +0300 From: nikol...@spbau.ru To: gmx-us...@gromacs.org Subject: [gmx-users] QM/MM
