The ELEC block of an APBS input file is used for polar solvation (electrostatics) calculations and has the following syntax:
where the indentation and linefeeds are included for clarity; only whitespace is needed in the input file. The
This section is the main component for polar solvation calculations in APBS
runs. There may be several ELEC sections, operating on different
molecules or using different parameters for multiple runs on the same
molecule. The order of the ELEC statement can matter since certain types
of boundary conditions (bcfl) can require information about previous calculations.
