> Isn't there some way to turn down the VdW via a distance cutoff or so? (EnableCutOff and SetVdWCutoff) I've never used these but hopefully they will prevent the pairwise generation of all of the VdW terms.
Curiously, this doesn't work. Enabling the cutoffs and setting to very small values still runs into the same memory problems. I may be wrong, but it seems that in forcefielduff.cpp:1417, if the atoms are not in _interGroups then the BitIsOn set by the cutoff will not be checked and SetupVDWCalculation is still called for every pair. I assume that the groups are not automatically generated? Fortunately, in my case, I have worked out that creating an OBConstraints and AddIgnore for every atom does exclude them from the vdW, but maybe this is a bug?
