Detailed Description

Classes specific to the Poisson equation.

Function Documentation

Mat ThunderEgg::Poisson::FastSchurMatrixAssemble2D	(	const Schur::InterfaceDomain< 2 > &	iface_domain,
		Poisson::FFTWPatchSolver< 2 > &	solver
	)

A fast algorithm for forming the Schur compliment matrix.

Currently this algorithm only supports the FFTWPatchSolver and it has to use either BiLinearGhostFiller or BiQuadraticGhostFiller

Parameters

iface_domain	the interface domain to form the Schur compliment matrix for
solver	the patch solver to use for the formation

Mat ThunderEgg::Poisson::FastSchurMatrixAssemble3D	(	const Schur::InterfaceDomain< 3 > &	iface_domain,
		Poisson::FFTWPatchSolver< 3 > &	solver
	)

A fast algorithm for forming the Schur compliment matrix.

Currently this algorithm only supports the FFTWPatchSolver and it has to use TriLinearGhostFiller

Parameters

iface_domain	the interface domain to form the schur compliment matrix for
solver	the patch solver to use for the formation
