[gmx-developers] virial

[Moore, Jonathan (J)]

Jason,

Perhaps GROMACS uses the atomic form of the virial rather than the molecular form?

I am trying to understand the virial calculations in order to zero the contributions from certain atoms. As I see it, only pairwise forces should be included and not things like dihedral forces. Is that correct? The code looks like it uses the entire force on every particle.
