Function Documentation

caleltsig_ani()

double caleltsig_ani	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		int	iel
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the metric structure.
iel	element index

Returns

0 if fail, -1 if orientation is reversed with regards to orientation of vertices, the computed quality otherwise.

Quality function identic to caltri_ani but puts a sign according to deviation to normal to vertices.

caleltsig_iso()

double caleltsig_iso	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		int	iel
	)

Here is the caller graph for this function:

diamelt()

double diamelt ( MMG5_pPoint  p0, MMG5_pPoint  p1, MMG5_pPoint  p2  )

inline

incircle()

double incircle ( MMG5_pPoint  p0, MMG5_pPoint  p1, MMG5_pPoint  p2, double *  o  )

inline

MMGS_inqua()

int MMGS_inqua	(	MMG5_pMesh	mesh,
		MMG5_pSol	met
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the metric structure.

Returns

0 if the worst element has a nul quality, 1 otherwise.

Print histogram of mesh qualities for classical storage of ridges metrics (so before the the MMG5_defsiz function call).

Here is the caller graph for this function:

MMGS_outqua()

int MMGS_outqua	(	MMG5_pMesh	mesh,
		MMG5_pSol	met
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the metric structure.

Returns

0 if the worst element has a nul quality, 1 otherwise.

Print histogram of mesh qualities for special storage of ridges metrics (after the MMG5_defsiz function call).

Here is the caller graph for this function:

MMGS_prilen()

int MMGS_prilen	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		int	metRidTyp
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the metric structure.
metRidTyp	Type of storage of ridges metrics: 0 for classic storage, 1 for special storage.

Returns

0 if fail, 1 otherwise.

Compute sizes of edges of the mesh, and displays histo.

typelt()

int8_t typelt	(	MMG5_pPoint	p[3],
		int8_t *	ia
