Charmm force
WebThe CHARMM force field contains topology and parameter information for the standard 20 amino acids, lipids, nucleic acids, and some other organic molecules. Thus, one can simulate any protein, DNA, or molecular systems which are composed of these basic ``building blocks". http://ffparam.umaryland.edu/
