Dreiding force field lammps

WebSummary. LAMMPS integrates Newton’s equations of motion for collections of atoms, molecules, or macroscopic particles that interact via short- or long-range forces with a variety of boundary conditions. Force fields supported include Amber, CHARMM, Dreiding, Embedded Atom potentials and Class2 force fields as well as user-defined force fields. WebThe -c or -class option selects the force field class, i.e which pair styles and bond styles and so on are required in the LAMMPS input file. Class I or class 1 uses similar combination of functional forms as Amber and Charmm force field and …
