Hi,
I'm currently trying to use fix qeq/comb on a complex system, where I only want to equilibrate the charges from two spatially separated groups of atoms. I originally wanted to use two fix qeq/comb commands, one on each group, but this does'nt seem to be working - only the last fix qeq/comb command is taken into account, and I guess it's probably intended.
So would it be correct to use the union of the groups as the argument of a unique fix qeq/comb command? Assuming that both groups have absolutely no interaction with one another.
Thanks,
Arthur
