MMG5_caltri33_ani()

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

Parameters

mesh	pointer to the mesh structure.
met	pointer to the meric structure.
pt	pointer to 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 to the mesh structure.
met	pointer to the meric structure.
ptt	pointer to 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.

inline

Parameters

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

Returns

The computed quality.

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

shift	value to shift the target lenght interval span of quality

Display histogram of edge length.

MMG5_minQualCheck()

int MMG5_minQualCheck	(	MMG5_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.
