Editing Force fields

'''Force fields''' consist of (hopefully) transferable parameters for molecular sub-units. They are designed to be applicable to a variety of molecular systems, in particular for [[flexible molecules]], over a (limited) range of thermodynamic conditions. Force fields usually consist of two parts; a functional form, where aspects of the molecular geometry, such as bonds, angles, torsions etc, are each assigned a mathematical function. The second aspect is a set of parameters, whose value varies depending on the atomic elements in question.
