What I'm doing, is unbiased-molecular dynamics simulation. in similar to
the following reference that the interaction energy is calculated.
I think the calculation of interaction energy is favourable for these type
of studies, only I'm not sure that the summation of above options is the
right way to obtain interaction energy.
