Detailed Description

template<Dune::Concept::GridView EntitySet>
struct Dune::PDELab::EntitySetPartition::Metis< EntitySet >

Partition set with entities split on several patches using METIS.

This is a partition on an entity set where entities seeds of the grid view are split using METIS and assigned to different patches of one label set. The patches are neighboring each other, thus, inducing a halo overlap in some entities of the partition.

Template Parameters

ES	Grid view to partition
