Detailed Description

Main class for computation of intersection of meshes of combined dimensions.

Controls different algorithms for computation of intersection. Computes intersection in the order:

1D-3D
2D-3D
2D-2D (uses results from 2D-3D) After computation, it transforms the internal intersection objects into proper output structure for further usage. The objects of different intersection types are stored in different vectors: intersection_storageXY_ ..

When we are on an element, we use element_intersections_ to get to all its intersections.

Member Typedef Documentation

◆ ILpair

typedef std::pair<unsigned int, IntersectionLocalBase *> MixedMeshIntersections::ILpair

For every element, stores list of intersections with this element.

intersection_map_[element index][i].first = other element index intersection_map_[element index][i].second = index pointer to the intersection object
