Detailed Description

template<int D>
class Pscf::Rpc::FilmFieldGenExt< D >

Field Generator for external fields in thin-film systems.

The parent FilmFieldGenExtBase class template defines all traits of a FilmFieldGenExt that do not require access to the System. This subclass defines all methods that need System access.

If the user chooses an FilmFieldGenExt object to generate external fields, the external fields will have the same shape as the mask, with a magnitude defined by a Flory–Huggins-like chi parameter. This class is specific to thin-film systems because it also allows for a different chi parameter to be defined on the top boundary than on the bottom, through user input arrays chi_bottom and chi_top. See Thin-Film Confinement for more information.

Member Function Documentation

◆ stress()

template<int D>

double Pscf::Rpc::FilmFieldGenExt< D >::stress ( int paramId ) const

virtual

Get contribution to the stress from the external fields.

The external fields defined by this class change in a non-affine manner upon changing the lattice parameter corresponding to normalVecId. Thus, if this lattice parameter is allowed to be flexible, the "stress" used to optimize the parameter must contain an additional term arising from the external fields. This method evaluates this term and returns its value.

Parameters

paramId index of the lattice parameter being varied
