SubdomainPartitioner()
Constructor, default initializes the internal Partitioner object to a MetisPartitioner so the class i...
MeshBase & mesh
The SubdomainPartitioner partitions the elements in "chunks" of user-specified subdomain ids...
std::vector< std::set< subdomain_id_type > > chunks
Each entry of "chunks" represents a set of subdomains which are to be partitioned together...
The libMesh namespace provides an interface to certain functionality in the library.
This is the MeshBase class.
Definition: mesh_base.h:68
The Partitioner class provides a uniform interface for partitioning algorithms.

std::unique_ptr< T > UniquePtr
Definition: auto_ptr.h:46
UniquePtr< Partitioner > _internal_partitioner
The internal Partitioner we use.
UniquePtr< Partitioner > & internal_partitioner()
Get a reference to the Partitioner used internally by the SubdomainPartitioner.
virtual void _do_partition(MeshBase &mesh, const unsigned int n) libmesh_override
Partition the MeshBase into n subdomains.
