I have Depending what termination criterion was satisfied in your EM, you might do better by increasing the number of steps, or decreasing the emtol .mdp file parameter (see manual 7.3) > tried my best to EM, but I only got Fmax<3e-4.

How can I make > the system to reach this point? As I suggested last time, perturbing it in a sensible manner and observing the behaviour is a way to test your minimization.
