Van der Waals 3D grid initialization benchmark

problem statement

We want to know the interaction energy between one atom [l_a] located at any grid point [i,j,k] and a fixed set of atoms [A]. We use the Van der Waals non-bonded interaction energy and Universal Force Field (UFF) parameters.

standard OCaml; before loop modification
