_MMG2_defaultmet_2d()

int _MMG2_defaultmet_2d	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		int	k,
		char	i
	)

Parameters

mesh	pointer toward the mesh
met	pointer toward the metric
k	elt index
i	vertex index in triangle k

Returns

0 if fail, 1 if success

Impose default metric (isotropic, with size hmax) at vertex i in triangle k.

Here is the caller graph for this function:

_MMG2_defmetbdy_2d()

int _MMG2_defmetbdy_2d	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		int	k,
		char	i
	)

Parameters

mesh	pointer toward the mesh
met	pointer toward the metric
k	index of the tria in which we work
i	index of the point on which we want to compute the metric

Returns

1 if success, 0 if fail

Calculate anisotropic metric tensor at (boundary) vertex i in triangle k on account of geometric approximation of the corresponding curve

_MMG2_defsiz_ani()

int _MMG2_defsiz_ani	(	MMG5_pMesh	mesh,
		MMG5_pSol	met
	)

Parameters

mesh	pointer toward the mesh
met	pointer toward the metric

Returns

0 if fail, 1 if success

Definition of an anisotropic metric tensor field based on the geometry of the domain; this tensor field is intersected by a user-defined tensor field

_MMG2_grad2met_ani()

int _MMG2_grad2met_ani	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		double *	m,
		double *	n,
		double	difsiz
	)

Parameters

mesh	pointer toward the mesh
met	pointer toward the metric
m	frist metric
n	second metric
difsiz	maximal size gap authorized by the gradation.

Returns

0 if fail or we don't need to modify the sizes. ier, where (ier & 1) if metric m is altered, and (ier & 2) if metric n is altered.

Perform simultaneous reduction of matrices m1 and m2, and truncate characteristic sizes so that the difference between two corresponding sizes is less than difsiz.
