In force.c, the innerloops are called with:
	  fr->bBHAM ? grps->estat.ee[egBHAM] : grps->estat.ee[egLJ],
The energies are stored in grps->estat.ee[egBHAM] or grps->estat.ee[egLJ]
and grps->estat.ee[egCOUL] (this is to support multiple energy groups)

In md.c these terms are summed using a call to sum_epot:
    /* Sum the potential energy terms from group contributions */
This function is in tgroup.c

Groeten, David.
