Assuming you have made proper use of energygrps in the .mdp file, you can
extract nonbonded terms between these groups from the .edr file using g_energy.
If you have not set energygrps, you can create a new .tpr file and use mdrun
-rerun to recalculate the energies from an existing trajectory or snapshot.
