Two methods are available : - Triangulation : the method of Jeffrey Grandy, 1999 (see \ref references) to intersect arbitrary polyhedra. The basic algorithm computes the -intersection of a tetrahedron with an arbitrary (possibly non convex) -polyhedron. Using splitting techniques, it is possible to transform +intersection of a target tetrahedron with an arbitrary (possibly non convex) +source polyhedron. Using splitting techniques, it is possible to transform the problem of computing the intersection between two general polyhedra into several tetrahedron-polyhedron intersection -calculations. For the moment it is only possible to remap fields on -meshes having mixed tetrahedral and hexahedral cells. When using a -mesh with hexahedral cells, several splitting techniques may be -employed depending mainly on whether the faces are planar or not. The -following options are available for the splitting: +calculations. The target polyhedron cell splitting into subtetrahedral cell operation +is performed upstream. For hexahedral target cells, the splitting can be parametrized +using SplittingPolicy option. This SplittingPolicy policy allows you to choose among +different split pattern mainly whether the faces of hexahedral are planar or not. +The following options are available for the splitting: - PointLocator : \b non \b conservative intersector based on the same principle than described in 2D.
