Function Documentation

MMGS_defsiz_iso()

int MMGS_defsiz_iso	(	MMG5_pMesh	mesh,
		MMG5_pSol	met
	)

Parameters

mesh	pointer to the mesh
met	pointer to the metric

Returns

1 if success, 0 if fail

Define isotropic size map at all vertices of the mesh, associated with geometric approx ; by convention, p0->h stores desired length at point p0

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 hausdorff distance

MMGS_set_metricAtPointsOnReqEdges()

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

Parameters

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

Returns

0 if fail, 1 otherwise

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

MMGS_sum_reqEdgeLengthsAtPoint()

static int MMGS_sum_reqEdgeLengthsAtPoint ( MMG5_pMesh  mesh, MMG5_pSol  met, MMG5_Hash *  hash, MMG5_pTria  pt, int8_t  i  )

inlinestatic

Parameters

mesh	pointer to the mesh structure.
met	pointer to the metric structure.
hash	edge hashtable.
pt	tria to process.
i	index of the edge of the tria pt that we process.

Returns

1 if success, 0 if fail.

If the edge i of the tria pt is seen for the first time, compute its euclidean length, add this length to the metric of the edge extremities and increment the count of times we have processed this extremities.
