Procedures#
setup
get_gradient_energy
get_polarization_bound_charge
get_eigenstrain
get_elastic_driving_force
get_landau_driving_force
get_gradient_driving_force
All the above subroutines have a parameter of type type_FerroelectricBase, which can be converted to types type_mupro_FerroelectricContext and type_mupro_inhomoFerroelectricContext as needed
