◆ MMG5_caltri33_ani()

double MMG5_caltri33_ani	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_pTria	pt
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the meric structure.
pt	pointer toward the triangle structure.

Returns: The computed quality.

Compute the quality of the surface triangle ptt with respect to an anisotropic metric and a classic storage of the ridges metrics.

◆ MMG5_caltri_ani()

double MMG5_caltri_ani	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_pTria	ptt
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the meric structure.
ptt	pointer toward the triangle structure.

Returns: The computed quality.

Compute the quality of the surface triangle ptt with respect to an anisotropic metric.

Warning: The quality is computed as if the triangle is a "straight" triangle.

◆ MMG5_caltri_iso()

double MMG5_caltri_iso	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_pTria	ptt
	)

inline

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the meric structure.
ptt	pointer toward the triangle structure.

Returns: The computed quality.

Compute the quality of the surface triangle ptt with respect to an isotropic metric.

void MMG5_displayLengthHisto	(	MMG5_pMesh	mesh,
		int	ned,
		double *	avlen,
		int	amin,
		int	bmin,
		double	lmin,
		int	amax,
		int	bmax,
		double	lmax,
		int	nullEdge,
		double *	bd,
		int *	hl,
		int8_t	shift
	)

Parameters

mesh	pointer toward the mesh structure.
ned	edges number.
avlen	pointer toward the average edges lengths.
amin	index of first extremity of the smallest edge.
bmin	index of second extremity of the smallest edge.
lmin	smallest edge length.
amax	index of first extremity of the largest edge.
bmax	index of second extremity of the largest edge.
lmax	largest edge length.
nullEdge	number of edges for which we are unable to compute the length
bd	pointer toward the table of the quality span.
hl	pointer toward the table that store the number of edges for eac
shift	value to shift the target lenght interval span of quality

Display histogram of edge length.

		int	imprim
	)

Parameters

ned	edges number.
amin	index of first extremity of the smallest edge.
bmin	index of second extremity of the smallest edge.
lmin	smallest edge length.
amax	index of first extremity of the largest edge.
bmax	index of second extremity of the largest edge.
lmax	largest edge length.
nullEdge	number of edges for which we are unable to compute the length
bd	pointer toward the table of the quality span.
hl	pointer toward the table that store the number of edges for eac
shift	value to shift the target lenght interval span of quality
imprim	verbosity level

Display histogram of edge length without the histo header

◆ MMG5_minQualCheck()

int MMG5_minQualCheck	(	int	iel,
		double	minqual,
		double	alpha
	)

Parameters

iel	index of the worst tetra of the mesh
minqual	quality of the worst tetra of the mesh (will be normalized by alpha)
alpha	normalisation parameter for the quality

Returns: 1 if success, 0 if fail (the quality is lower than MMG5_NULKAL).

Print warning or error messages depending on the quality of the worst tetra of the mesh.
