The reaction field method is sometimes known as the Onsager reaction field.
Vapour-liquid equilibria
Anisotropic models
Monte Carlo simulations have been performed for dipolar anisotropic models (hard spherocylinders (Ref. 1) and the Gay-Berne model (Ref. 2)), both indicating that the results for the reaction field and the Ewald sum are equivalent. However, the reaction field presents a considerable reduction in the computer time required.
