Member Function Documentation

integrate()

void ProcessLib::SurfaceFlux::integrate	(	std::vector< GlobalVector * > const &	x,
		MeshLib::PropertyVector< double > &	balance,
		double const	t,
		MeshLib::Mesh const &	bulk_mesh,
		std::vector< std::size_t > const &	active_element_ids,
		std::function< Eigen::Vector3d(std::size_t const, MathLib::Point3d const &, double const, std::vector< GlobalVector * > const &)> const &	getFlux
	)

Executes for each element of the mesh the local integration procedure.

Parameters

x	The global solution the integration values will be fetched of.
balance	The vector the integration results will be stored in.
t	The balance will be computed at the time t.
bulk_mesh	Stores a reference to the bulk mesh that is needed to fetch the information for the integration over the surface mesh.
active_element_ids	The IDs of active elements. It is empty if there is no deactivated subdomain.
getFlux	function that calculates the flux in the integration points of the face elements of the bulk element that belongs to the surface.
