MMG3D_coledges()

int MMG3D_coledges	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_int	k,
		int	i
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the metric structure.
k	index of a tetra
i	index of point to delete in tetra k.

Returns

1 if success, 0 if we can't delete the point.

Try to remove point i of tet k, try the three edges of k containing i.

		MMG5_int	k,
		int	i
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the metric structure.
PROctree	pointer toward the PROctree structure.
k	index of a tetra
i	index of point to delete in tetra k.

Returns

1 if success, 0 if we can't delete the point.

Try to delete the point i of tet k. Try all the edges containing i.

		MMG3D_pPROctree	PROctree,
		MMG5_int	k
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the metric structure.
k	index of a tetra

Returns

1 if we move one of the vertices, 0 otherwise.

Try to move the vertices of the tetra k to improve its quality.

	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the metric structure.
PROctree	pointer toward the PROctree structure.
k	index of a tetra

Returns

1 if success, 0 if fail.

Try to optimize the tetra k. This tetra has a face on the boundary.
