MolEnergy is a library of routines for efficiently computing molecular free energies. The primary components are:

• Octree-based approximation algorithms for computing pairwise Lennard-Jones and Coulombic potentials, Born radii and generalized Born polarization energy,
• Nonuniform fast Fourier transform approach (using NFFT) to computing generalized Born polarization energy, and
• Kernel independent fast multipole-based boundary element solver for the Poisson-Boltmzann equation (using KIFMM3d and PETSc).

Most MolEnergy functionality can be interfaces through TexMol.

Coming soon: stand alone, command-line interface to MolSurf package.

MolEnergy commands can be called through the Utilities menu of TexMol.
