[gmx-users] electrostatic energy calculation

[Alexander Alexander]

Hi there,

g_energy or gmx energy just lists the short-ranged non-bonded potential
energies of those species which have been already indicated in *.mdp file
by "energygrps", like energygrps   = A B C, then g_energy would offer you
something like  Coul-SR: A-B , LJ-SR: B-C and so on.

Cheers,
Alex
