Member Enumeration Documentation

SBElementType

enum mfem::ShiftedFaceMarker::SBElementType

Element type related to shifted boundaries (not interfaces). For more than 1 level-set, we set the marker to CUT+level_set_index to discern between different level-sets.

Enumerator
INSIDE
OUTSIDE
CUT

Member Function Documentation

ListEssentialTDofs()

void mfem::ShiftedFaceMarker::ListEssentialTDofs	(	const Array< int > &	elem_marker,
		const Array< int > &	sface_dof_list,
		Array< int > &	ess_tdof_list,
		Array< int > &	ess_shift_bdr ) const

List the dofs that will be inactive for the computation on the surrogate domain. This includes dofs for the elements located outside the true domain (and optionally, for the elements cut by the true boundary, if include_cut_cell = false) minus the dofs that are located on the surrogate boundary.

Definition at line 202 of file marking.cpp.

ListShiftedFaceDofs()

void mfem::ShiftedFaceMarker::ListShiftedFaceDofs	(	const Array< int > &	elem_marker,
		Array< int > &	sface_dof_list ) const

List dofs associated with the surrogate boundary. If include_cut_cell = false, the surrogate boundary includes faces between elements cut by the true boundary and the elements that are located inside the true domain. If include_cut_cell = true, the surrogate boundary is the faces between elements outside the true domain and the elements cut by the true boundary.

ListShiftedFaceDofs2()

void mfem::ShiftedFaceMarker::ListShiftedFaceDofs2 ( const Array< int > & elem_marker, Array< int > & sface_dof_list ) const

MarkElements()

void mfem::ShiftedFaceMarker::MarkElements	(	const ParGridFunction &	ls_func,
		Array< int > &	elem_marker )

Mark all the elements in the mesh using the SBElementType. A point is considered inside when the level set function is positive. Assumes the ExchangeFaceNbrData() has been called for pmesh, ls_func.
