A force field has 2 parts: the formulas that define it and the
|
||||
coefficients used for a particular system. Here we only discuss
|

formulas implemented in LAMMPS that correspond to formulas commonly

used in the CHARMM, AMBER, and DREIDING force fields. Setting

coefficients is done in the input data file via the

"read_data"_read_data.html command or in the input script with
|

commands like "pair_coeff"_pair_coeff.html or

COMPASS is a general force field for atomistic simulation of
|

common organic molecules, inorganic small molecules, and polymers which
|
||||
was developed using ab initio and empirical parametrization techniques.

See "(Sun)"_#howto-Sun for a description of the COMPASS force field.

These style choices compute force field formulas that are consistent

with the COMPASS force field. See each command's

documentation for the formula it computes.
