apbs.input_file.calculate.nonpolar
Note
This command has been ported to the new APBS syntax (see new_input_format): see Nonpolar.surface_tension for more information.
This keyword specifies the surface tension coefficient for apolar solvation models.
gamma { value }where value is a floating point number designating the surface tension in units of kJ mol-1 Å-2. This term can be set to zero to eliminate the SASA (solvent-accessible surface area) contributions to the apolar solvation calculations.
