The computational effort of biomolecular simulations can be significantly reduced by means of implicit solvent models in which the energy generally contains a correction depending on the surface area and/or the volume of the molecule. In this article, we present simple derivation of exact, easy‐to‐use analytical formulas for these quantities and their derivatives with respect to atomic coordinates. In addition, we provide an efficient, linear‐scaling algorithm for the construction of the power diagram required for practical implementation of these formulas. Our approach is implemented in a C++ header‐only template library. © 2011 Wiley Periodicals, Inc. J Comput Chem, 2011
