Inheritance diagram for Dumux::DistributedIntersectionEntitySet< DomainEntitySet, TargetEntitySet >:

Description

template<class DomainEntitySet, class TargetEntitySet>
class Dumux::DistributedIntersectionEntitySet< DomainEntitySet, TargetEntitySet >

The intersections are distributed by domain ownership: each process holds exactly those intersections whose domain (first) entity it owns. The union over all processes equals the result of a sequential intersection of the global entity sets. The target (second) entity of an intersection may be owned by a remote process; it is identified by its global (rank, local index) identifier rather than by a local entity.

Note: This currently returns the raw (triangulated) intersections without the mixed-dimensional neighbor merging done by Dumux::IntersectionEntitySet.
