Function Documentation

MMG2D_defsiz_iso()

int MMG2D_defsiz_iso	(	MMG5_pMesh	mesh,
		MMG5_pSol	met
	)

Parameters

mesh	pointer toward the mesh
met	pointer toward the metric

Returns

0 if fail, 1 otherwise

New version for the definition of a size map; takes into account the curvature of the external and internal curves present in the mesh

1) Size at internal points

Step 1: Set metric at points belonging to a required edge: compute the metric as the mean of the length of the required eges passing through the point

Step 2: size at non required internal points

Step 3: Minimum size feature imposed by the boundary edges

If local parameters are provided: size truncation on the entire mesh

MMG2D_set_metricAtPointsOnReqEdges()

int MMG2D_set_metricAtPointsOnReqEdges	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		int8_t	ismet
	)

Parameters

mesh	pointer toward the mesh
met	pointer toward the metric
ismet	1 if user provided metric

Returns

0 if fail, 1 otherwise

Compute the metric at points on required edges as the mean of the lengths of the required eges to which belongs the point. The processeed points are marked with flag 3.

MMG2D_sum_reqEdgeLengthsAtPoint()

int MMG2D_sum_reqEdgeLengthsAtPoint	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_pTria	pt,
		int8_t	i
	)

Parameters

mesh	pointer toward the mesh structure.
met	pointer toward the metric structure.
pt	tetra to process.
i	index of the edge of the tetra pt that we process.

Returns

1 if success, 0 if fail.

Compute the euclidean length of the edge i of the tria pt, add this length to the metric of the edge extremities and increment the count of times we have processed this extremities.
