Function Documentation

chkswp()

int chkswp	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_int	k,
		int	i,
		int8_t	typchk,
		double(*)(MMG5_pMesh, MMG5_pSol, MMG5_int, MMG5_int, int8_t)	MMGS_lenEdg,
		double(*)(MMG5_pMesh, MMG5_pSol, MMG5_pTria)	MMGS_caltri
	)

Parameters

mesh	pointer to the mesh
met	pointer to the metric
k	index of the element in wich we perform the edge swap
i	index of the edge to swap
typchk	type of check to perform
MMGS_lenEdg	pointer to the suitable fct to compute edge lengths depending on presence of input metric, metric type (iso/aniso) and typchk value (i.e. stage of adaptation)
MMGS_caltri	pointer to the suitable fct to compute tria quality depending on presence of input metric, metric type (iso/aniso) and typchk value (i.e. stage of adaptation)

Check whether edge i of triangle k should be swapped for geometric approximation purposes

Here is the caller graph for this function:

swapar()

int swapar	(	MMG5_pMesh	mesh,
		MMG5_int	k,
		int	i
	)

Parameters

mesh	poiner toward the mesh structure.
k	elt index.
i	index of the elt edge to swap.

Returns

1

Warning

the quality of the resulting triangles is not checked here... It must be checked outside to prevent the creation of empty elts.
