Do you want different weightings for multiple bonds?: "yes" means that if part of a molecule or ion is bonded to more than one other species that you want to treat the free energy of crystallisation differently depending upon the coordination number. "no" means that all coordinations are weighted equally.
Weightings for multiple bonds
What scaling for group x coordination y: this is the weighting for multiple coordinations that will be applied to the interaction strength if you have selected after checking "yes" for "Do you want species grouped on [Simulation options] tab.
