Function Documentation

MMG3D_swap23()

int MMG3D_swap23	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_int	k,
		int8_t	metRidTyp,
		int	ifac,
		int	conf0,
		MMG5_int	adj,
		int	conf1
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the sol structure.
k	index of the tetrahedron with multiple boundary faces (to be swapped).
metRidTyp	metric storage (classic or special)
ifac	face of the tetra k that give the best results for the swap23
conf0	detected configuration for the swap23 of the tetra k
adj	neighbour of the tetra k through the face ifac (4*k1+ifac1)
conf1	detected configuration for the swap23 of the tetra adj/4

Returns

-1 if lack of memory, 0 if fail to swap, 1 otherwise.

Search an adjacent to the tetra k and perform swap 2->3 (the common face of the 2 tetra is destroyed and replaced by a common edge used by the three new elts).

Remarks

used in anatet4 to remove the tetra with multiple boundary faces.

Neighbouring element with which we will try to swap

MMG5_chkswpbdy()

int MMG5_chkswpbdy	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		int64_t *	list,
		int	ilist,
		MMG5_int	it1,
		MMG5_int	it2,
		int8_t	typchk
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the metric structure.
list	pointer toward the shell of the edge.
ilist	pointer toward the size of the shell of the edge.
it1	first element of the open shell.
it2	last element of the open shell.
typchk	type of checking permformed for edge length (hmin or LSHORT criterion).

Returns

-1 if fail, 0 if we can not swap the edge, 1 otherwise.

Check whether edge whose shell is provided should be swapped for geometric approximation purposes (the 2 surface triangles are also provided).

		int	ret,
		MMG5_int	it1,
		MMG3D_pPROctree	PROctree,
		int8_t	typchk
	)

Parameters

mesh	pointer toward the mesh structure
met	pointer toward the solution structure
list	pointer toward the shell of the edge
ret	dobble of the number of tetrahedra in the shell
it1	boundary face carrying the beforehand tested terminal point for collapse
PROctree	pointer toward the PROctree structure in Delaunay mode, NULL pointer in pattern mode.
typchk	type of checking permformed for edge length (hmin or LSHORT criterion).

Returns

-1 if lack of memory, 0 if fail to swap, 1 otherwise

Swap boundary edge whose shell is provided.
