Chris, Also, if your C60 is hollow, I can imagine that it might exclude solvent atoms from the inside, in which case you are going to have a big convergence issue as solvent begins to interpenetrate with the C60, which may lead to noise problems when this starts to happen, whatever soft core

Hi, Hi gmx-users, I have tried to calculate the free energy of transfer of a solute between two solvents by thermodynamic integration. However, the dgdl plot I have obtained is not smooth enough to ensure accuracy. I have used a non homogeneous spacing for lambda. The first is from 0.0 to
