Detailed Description

Construction of semi-conformal interface information.

The current algorithm has the following limitations:

it only applies to surfaces composed solely of quadrangles in 3D and edges in 2D.
a semi-conformal interface is composed of two surfaces, one called slave and the other master. The slave surface contains the set of faces that are most meshed. This surface is specified by the user. The master surface is the one containing the most coarsely meshed faces.

The goal is to calculate the set of master and slave faces, for each master face the list of its slave faces and for each slave face node its iso-barycentric coordinates in the corresponding master face.

The algorithm works as follows:

we know the set of slave faces. We must determine the set of master faces. To do this, we iterate over all slave faces and mark their nodes. We then just need to iterate over all external faces of the mesh and if a face has all its nodes marked and is not slave, it is a master face.
TODO CONTINUE.

◆ _computeMasterInterface()

void Arcane::mesh::TiedInterfaceBuilder::_computeMasterInterface ( )

private

Determines the master surface of the interface.

Considering that the mesh is semi-conforming, this means that all nodes of the master faces of the interface belong to a slave face. It is therefore enough to determine these master faces by iterating through the list of slave faces, marking the nodes of these faces. A face is then considered master if all of its nodes are marked.

Note: This algorithm can potentially return more master faces than there actually are in the case where a cell has welds on several sides. This is not very serious because no slave face will be found for these master faces and they will be removed from the group of master faces.

◆ _findProjection()

GeometricUtilities::ProjectionInfo Arcane::mesh::TiedInterfaceBuilder::_findProjection	(	const TiedInterfaceFace &	face,
		Real3	point )

private

Calculates the projection of a point onto a face.

In 2D, the face is an edge and the projection is simple.

In 3D, if the face is a triangle, the projection is also simple since it is the projection onto a plane. For a face having more than 3 nodes, its nodes are not necessarily coplanar. The face is then decomposed into triangles whose vertex is the barycenter of the face and we calculate the projection of the point point onto each of these triangles. We therefore have as many projections as triangles. We keep which is inside one of these triangles. It may happen for reasons related to numerical calculation that the point is actually inside the face but in none of its triangles (for example, if it is on a diagonal). In this case, we take the one that is closest to the point point.
