There are various methods of computing the Helmholtz energy function of solid phases. The most widely used is the procedure (See References 3 and 4) based on the techniques of thermodynamic integration. The usual implementations derive from the paper by Frenkel and Ladd (See Ref.3) which makes use of the Einstein crystal. Recently, a more efficient formalism has been developed by N. G. Almarza (see Ref. 5).
