Monte Carlo calculation of the Helmholtz free energy of molecular crystals consisting of rigid molecules.

At the moment the code available for downloading from the calculates the free energy of sII clathrate filled with hydrogen molecules in the small cages and with 1,3-dioxolane (C3H6O2) molecules in the large cages. More to come soon!
