Function Documentation

◆ boulechknm()

int boulechknm	(	MMG5_pMesh	mesh,
		MMG5_int	start,
		int	ip,
		MMG5_int *	list
	)

Parameters

mesh	pointer to the mesh structure.
start	index of tetra to start to compute the ball.
ip	index of point in tetra start for which we want to compute the ball.
list	pointer to the computed ball of point.

Returns: size of list if success, -size if overflow, 0 if cfg is non-manifold.

Find all triangles sharing ip, \(list[0] = start\) . Do not stop when crossing ridge. Check whether resulting configuration is manifold.

Definition at line 51 of file boulep_s.c.

Here is the caller graph for this function:

◆ bouletrid()

int bouletrid	(	MMG5_pMesh	mesh,
		MMG5_int	start,
		MMG5_int	ip,
		int *	il1,
		MMG5_int *	l1,
		int *	il2,
		MMG5_int *	l2,
		MMG5_int *	ip0,
		MMG5_int *	ip1
	)

Parameters

mesh	pointer to the mesh structure.
start	index of the starting triangle.
ip	index of the looked ridge point.
il1	pointer to the first ball size.
l1	pointer to the first computed ball (associated to n1's side).
il2	pointer to the second ball size.
l2	pointer to the second computed ball (associated to n2's side).
global	ip0 index of the first extremity of the ridge.
global	ip1 index of the second extremity of the ridge.

Returns: 0 if fail, 1 otherwise.

Computation of the two balls of a ridge point: the list l1 is associated to normal n1's side. ip0 and ip1 are the indices of the 2 ending point of the ridge. Both lists are returned enumerated in direct order.

◆ caleltsig_ani()

double caleltsig_ani	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_int	iel
	)

Parameters

mesh	pointer to the mesh structure.
met	pointer to the metric structure.
iel	element index

Returns: 0 if fail, -1 if orientation is reversed with regards to orientation of vertices, the computed quality otherwise.

Quality function identic to caltri_ani but puts a sign according to deviation to normal to vertices.

Define size at points by intersecting the surfacic metric and the physical metric.

The output metric is:

at singular points: isotropic
at ridge points: anisotropic in the orthonormal basis defined by the tangent at the ridge and the normal at each portion of surface.
at surface boundary points: anisotropic in an orthonormal basis difined in the tangent plane and the direction normal to this plane.

Warning: What we are doing on non-manifold points has to be improved: as such points are marked as MG_CRN and MG_REQ, we first try to call MMG5_defmetsin that likely fails (because MMG5_boulet don't work for non-manifod points due to the missing of consistent adjacencies relationships), then we call MMG5_defUninitSize and we set hmax on non-manifold points. Note that the building of adjacency table depends on the initial mesh numbering, thus, in certain cases, MMG5_boulet will succeed...

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: Travel all the points (via triangles) in the mesh and set metric tensor

search for unintialized metric

Remark: as non manifold points are marked as CRN and REQ, we first try to call defmetsin that fails (because MMG5_boulet don't work for non-manifod points), then we pass here and we set hmax on non-manifold points

Returns: 1 if succeed, 0 if fail

Remarks: need the normal at vertices.; hmax/hmin may be not setted here so we can't use it.

Compute the unit metric tensor at mesh vertices (from edges passing through the vertices).

Increment base marker to detect points already processed

Step 1: treat non-manifold points: travel triangle edges and add edge contribution to extremities (we have to do that because ball of non-manifold points can't be computed)

Corner point (no normal at vertex): if the corner defines an angle we can compute the 3D unit tensor (non singular), in the other cases (corner along a flat surface, for example because it is at the intersection of 3 specific edges or because it is provided by the user) we will project the edges onto the tangent plane and compute the 2D unit tensor (as for required and regular points)

Required point (no normal at vertex): projection of edges onto the tangent plane and computation of the 2D unit tensor

Ridge point (2 normals): normally we can compute the 3D unit tensor. If the angle is too flat, the computation fails and we try to compute the 2D unit tensor on the tangent plane of the point.

Regular or reference point: projection of edges onto the tangent plane and computation of the 2D unit metric tensor

Step 3: check computed metric
