findIfTringleHasThreeNodesOnInternalSurfaceSkin()

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

Find if triangle has three nodes on internal surface skin.

Internal surface skin is a set of edges in interface of the body on boundary of surface. This set of edges is called surface front. If surface face has three nodes on surface front, non of the face nodes is split and should be removed from surface if it is going to be split.

Parameters

sideset	meshset with surface
mesh_bit_level	bit ref level of the volume mesh
recursive	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
	)

create two children meshsets in the meshset containing tetrahedral on two sides of faces

Get tets adj to faces. Take skin form tets and get edges from that skin. Take skin form triangles (the face). Subtrac skin faces edges form skin edges in order to get edges on the boundary of the face which is in the volume of the body, but is not on the boundary. Each child set has a child containing nodes which can be split and skin edges. After that simply iterate under all tets on one side which are adjacent to the face are found. Side tets are stored in to children meshsets of the SIDESET meshset.

		const bool	recursive = false,
		int	verb = QUIET
	)

split nodes and other entities of tetrahedral in children sets and add prism elements

The all new entities (prisms, tets) are added to refinement level given by bit

Parameters

meshset	meshset to get entities from
BitRefLevel	new level where refinement would be stored
msId	meshset ID imported from cubit
cubit_bc_type	type of meshset (NODESET, SIDESET or BLOCKSET and more)
add_interface_entities	meshset which contain the interface
recursive	if true parent meshset is searched recursively

Each inteface face has two tags, const int def_side[] = {0}; rval = moab.tag_get_handle("INTERFACE_SIDE",1,MB_TYPE_INTEGER, th_interface_side,MB_TAG_CREAT|MB_TAG_SPARSE,def_side); CHKERRQ_MOAB(rval);

First tag inform about inteface side, second tag inform about side adjacent inteface element.

split nodes and other entities of tetrahedrons in children sets and add prism elements

Parameters

meshset
Refinement	bit level of new mesh
inhered_from_bit_level	inhered nodes and other entities form this bit level.
add_interface_entities	add prism elements at interface
recursive	do meshesets in the meshset

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