Some versions of this command have been ported to the new APBS syntax (see YAML- and JSON-format input files):

  • Nonpolar calculations:
    See Nonpolar.solvent_density() for more information.

This keyword specifies the bulk solvent density. This coefficient multiplies the integral term of the apolar model discussed above and can be set to zero to eliminate integral contributions to the apolar solvation calculation. The syntax is:

bconc <density>

where density is a floating point number giving the bulk solvent density in Å-3.
