The definition of the element_iterator struct.
Definition: mesh_base.h:1476
The MappedSubdomainPartitioner partitions the elements based on their subdomain ids.
MeshBase & mesh
IterBase * end
Also have a polymorphic pointer to the end object, this prevents iterating past the end...
virtual void _do_partition(MeshBase &mesh, const unsigned int n) libmesh_override
Partition the MeshBase into n subdomains.
The libMesh namespace provides an interface to certain functionality in the library.
virtual UniquePtr< Partitioner > clone() const libmesh_override
This is the MeshBase class.
Definition: mesh_base.h:68
The Partitioner class provides a uniform interface for partitioning algorithms.

virtual void partition_range(MeshBase &mesh, MeshBase::element_iterator it, MeshBase::element_iterator end, const unsigned int n) libmesh_override
Called by the SubdomainPartitioner to partition elements in the range (it, end).
std::map< subdomain_id_type, processor_id_type > subdomain_to_proc
Before calling partition() or partition_range(), the user must assign all the Mesh subdomains to cert...
