◆ MMG2D_caltri_ani()

double MMG2D_caltri_ani	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_pTria	pt
	)

Definition at line 121 of file quality_2d.c.

◆ MMG2D_caltri_iso()

double MMG2D_caltri_iso	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_pTria	pt
	)

Parameters

pointer	to the mesh
pointer	to the metric (for compatibility with aniso interface)
pt	pointer to the tria

Returns: non-normalized quality if success, 0 if triangle is null or inverted.

Compute quality of the triangle pt when the supplied metric is isotropic; return 0 in the case that the triangle has inverted orientation.

	)

Parameters

a	coordinates of first vertex of tria
b	coordinates of second vertex of tria
c	coordinates of third vertex of tria

	)

Parameters

mesh	pointer to the mesh structure.
met	pointer to the metric structure.

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

Print histogram of mesh qualities.
