APBS (The Adaptive Poisson-Boltzmann Solver) is a macromolecular electrostatics calculation program that solves the equations of continuum electrostatics for large biomolecular assemblages. The APBS code is accompanied by extensive documentation for both users and programmers and is supported by a variety of utilities for preparing calculations and analyzing results. PyMOL can display the results of the calculations as an electrostatic potential molecular surface. Most APBS functionality is also available through online web server (http://www.poissonboltzmann.org/).
