Function Documentation

MMG5_split2_sim()

int MMG5_split2_sim	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_int	k,
		MMG5_int *	vx
	)

Parameters

mesh	pointer to the mesh structure.
met	pointer to the metric structure.
k	index of element to split.
vx	\(vx[i]\) is the index of the point to add on the edge i.

Returns

0 if split leads to invalid element, else 1.

Simulate the splitting of element k along the 2 edges i1 and i2. Check that the new triangles are not empty (otherwise we can create a 0 surface triangle).

MMGS_simbulgept()

int MMGS_simbulgept	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_int	k,
		int	i,
		MMG5_int	ip
	)

Parameters

mesh	pointer to the mesh structure.
met	pointer to the metric structure.
k	index of the starting triangle.
i	local index of the edge to split in k.
ip	index of the point that we try to create.

Returns

0 if final position is invalid or if computation of bezier patch fails, 1 if all checks are ok.

Simulate the creation of the point ip, to be inserted at an edge. Check that the new triangles are not empty (otherwise we can create a 0 surface triangle).

Remarks

Don't work for non-manifold edge.

Parameters

mesh	pointer to the mesh structure.
met	pointer to the metric structure.
k	index of element to split.
