Function Documentation

MMG5_chkswpgen()

MMG5_int MMG5_chkswpgen	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_int	start,
		int	ia,
		int *	ilist,
		int64_t *	list,
		double	crit,
		int8_t	typchk
	)

Parameters

mesh	pointer to the mesh structure
met	pointer to the metric structure.
start	tetrahedra in which the swap should be performed
ia	edge that we want to swap
ilist	pointer to store the size of the shell of the edge
list	pointer to store the shell of the edge
crit	improvment coefficient

Returns

-1 if fail, 0 if we cannot swap, the index of point corresponding to the swapped configuration otherwise ( \(4*k+i\)).

Parameters

typchk

type of checking permformed for edge length (hmin or LSHORT criterion).

Check whether swap of edge ia in start should be performed, and return \(4*k+i\) the index of point corresponding to the swapped configuration. The shell of edge is built during the process.

MMG5_swpgen()

int MMG5_swpgen	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_int	nconf,
		int	ilist,
		int64_t *	list,
		MMG3D_pPROctree	PROctree,
		int8_t	typchk
	)

Parameters

mesh	pointer to the mesh structure.
met	pointer to the sol structure.
nconf	configuration.
ilist	number of tetrahedra in the shell of the edge that we want to swap.
list	pointer to the shell of the edge that we want to swap.
PROctree	pointer to 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.

Perform swap of edge whose shell is passed according to configuration nconf.

First step : split of edge (na,nb)

Second step : collapse of np towards enhancing configuration
