findFacesWithThreeNodesOnInternalSurfaceSkin()

MoFEMErrorCode MoFEM::PrismInterface::findFacesWithThreeNodesOnInternalSurfaceSkin	(	const EntityHandle	sideset,
		const BitRefLevel	mesh_bit_level,
		const bool	recursive,
		Range &	faces_with_three_nodes_on_front,
		int	verb = QUIET
	)

Find triangles which have three nodes on internal surface skin.

Internal surface skin is a set of all edges on the boundary of a given surface inside the body. This set of edges is also called the surface front. If a triangle has three nodes on the surface front, none of these nodes can be split. Therefore, such a triangle cannot be split and should be removed from the surface.

Parameters

sideset	meshset with surface
mesh_bit_level	bit ref level of the volume mesh
recursive	if true search in sub-meshsets
faces_with_three_nodes_on_front	returned faces
verb	verbosity level

Returns

error code

MoFEMErrorCode MoFEM::PrismInterface::getSides	(	const EntityHandle	sideset,
		const BitRefLevel	mesh_bit_level,
		const bool	recursive,
		int	verb = QUIET
	)

Store tetrahedra from each side of the interface in two child meshsets of the parent meshset.

Additional third child meshset contains nodes which can be split and skin edges

Parameters

sideset	parent meshset with the surface
mesh_bit_level	interface is added on this bit level
recursive	if true parent meshset is searched recursively
verb	verbosity level

Note

if bit_level == BitRefLevel.set() then interface will be added on all bit levels

1. Get tets adjacent to nodes of the interface meshset.
2. Take skin faces from these tets and get edges from that skin.
3. Take skin from triangles of the interface.
4. Subtract edges of skin faces from skin of triangles in order to get edges in the volume of the body, and not on the interface boundary.
5. Iterate between all triangles of the interface and find adjacent tets on each side of the interface

	)

Store tetrahedra from each side of the interface separately in two child meshsets of the parent meshset.

Additional third child meshset contains nodes which can be split and skin edges

Parameters

msId	Id of meshset
cubit_bc_type	type of meshset (NODESET, SIDESET or BLOCKSET and more)
mesh_bit_level	interface is added on this bit level
recursive	if true parent meshset is searched recursively
verb	verbosity level

Note

		const EntityHandle	sideset,
		const bool	add_interface_entities,
		const bool	recursive = false,
		int	verb = QUIET
	)

Split nodes and other entities of tetrahedra on both sides of the interface and insert flat prisms in-between.

Parameters

meshset	volume meshset containing 3D entities around the interface
bit	bit ref level on which new entities will be stored
inhered_from_bit_level	inherit nodes and other entities form this bit level
inhered_from_bit_level_mask	corresponding mask
sideset	meshset with surface
add_interface_entities	if true add prism elements at interface
recursive	if true parent meshset is searched recursively
verb	verbosity level

Note

Parent meshset must have three child meshsets: two with tetrahedra from each side of the interface, third containing nodes which can be split and skin edges

inhered_from_bit_level needs to be specified for some meshsets with interfaces. Some nodes on some refinement levels are dividing edges but not splitting faces. Inheriting those nodes will not split faces.

bit	bit ref level on which new entities will be stored
sideset	meshset with surface
add_interface_entities	if true add prism elements at interface
recursive	if true parent meshset is searched recursively
verb	verbosity level

Note

Parent meshset must have three child meshsets: two with tetrahedra from each side of the interface, third containing nodes which can be split and skin edges

splitSides() [3/3]

MoFEMErrorCode MoFEM::PrismInterface::splitSides	(	const EntityHandle	meshset,
		const BitRefLevel &	bit,
		const int	msId,
		const CubitBCType	cubit_bc_type,
		const bool	add_interface_entities,
		const bool	recursive = false,
		int	verb = QUIET
	)

Split nodes and other entities of tetrahedra on both sides of the interface and insert flat prisms in-between.

Parameters

meshset	volume meshset containing 3D entities around the interface
bit	bit ref level on which new entities will be stored
msId	meshset ID of the surface
cubit_bc_type	type of meshset (NODESET, SIDESET or BLOCKSET and more)
add_interface_entities	if true add prism elements at interface
recursive	if true parent meshset is searched recursively
verb	verbosity level

Note

Parent meshset must have three child meshsets: two with tetrahedra from each side of the interface, third containing nodes which can be split and skin edges
