It depends on the function type. See the table "Intramolecular interaction definitions" in chapter 5 of the gromacs manual. There you can se the units associated with the different kinds of interactions. Erik Vitaly V. Chaban skrev: Hi, In what units does gromacs MD engine treats harmonic bo

Hi, In what units does gromacs MD engine treats harmonic bond constants? In the tutorial, there is a hint about fourth-power potential (related to GROMOS-96 FF) which I guess should have a constant in [kJ/mol/nm^4], but not in [kJ/mol/nm^2]. Although it seems by the absolute value that in the exis
