capytaine.green_functions.hams module

class capytaine.green_functions.hams.FinGreen3D(*, nb_dispersion_roots=200)

Bases: AbstractGreenFunction

Wrapper for the Fortran implementation of the finite depth Green function of [Liu et al.].

Uses the same implementation as Delhommeau() for the Rankine and reflected Rankine terms.
