CS-NPSA
Nonpolar Surface Area from Continuum Solvation
The Continuum Solvation Nonpolar Surface Area (CS-NPSA) package is a general purpose program suite for defining and computing nonpolar surface areas based on continuum solvation models.
It is based on the classification of individual surface elements representing the solvent accessible surface used for the description of the polarized charge density elements in the CS models.
