MMG2D_norver()

int MMG2D_norver	(	MMG5_pMesh	mesh,
		int	ref
	)

Parameters

mesh	pointer toward the mesh structure
ref	reference of the boundary to analyze (analyze all the boundaries if MMG5_UNSET)

Returns

1 if success, 0 if fail.

Calculate normal vectors at vertices of the mesh.

Mark the points that we don't want to analyze

Parameters

mesh	pointer toward the mesh

Returns

0 if fail, 1 if success

Regularize normal vectors at boundary non singular edges with a Laplacian / antilaplacian smoothing

Parameters

mesh	pointer toward the mesh

Returns

1 if success, 0 if fail

Set tags GEO, BDY and REF to triangles and points by traveling the mesh; count number of subdomains or connected components

Step 1: Tags setting from triangles analysis

Step 2: Mark the edges at interface between tria and quads as nosurf and required

Parameters

mesh	pointer toward the mesh structure
ref	reference of the boundary to analyze (analyze all the boundaries if MMG5_UNSET)

Returns

1 if success, 0 if fail.

Identify singularities in the mesh.

Mark the points that we don't want to analyze
