[gmx-users] potential energy of a system

[Mark Abraham]

Hi,

The total potential energy has everything by definition, so I don't know
what you're asking.

Additivity of the components of the potential energy is an artefact of the
construction of the model physics. While it is true that different physical
phenomena underlie some of the components, the parameterization of the
force field did not target meaningful decomposition of the potential
energy. But you might be able to benefit from fortuitous cancellation
effects when comparing such things.
