virtual void _do_partition(MeshBase &mesh, const unsigned int n) override
Partition the MeshBase into n subdomains.
virtual void _do_partition(MeshBase &mesh, const unsigned int n) override
Partition the MeshBase into n subdomains.
MeshBase & mesh
The libMesh namespace provides an interface to certain functionality in the library.
This is the MeshBase class.
Definition: mesh_base.h:74
PartitionerType
Defines an enum for mesh partitioner types.
virtual ~MortonSFCPartitioner()=default
MortonSFCPartitioner & operator=(const MortonSFCPartitioner &)=default
The MortonSFCPartitioner uses a Morton space filling curve to partition the elements.
The SFCPartitioner uses a Hilbert or Morton-ordered space filling curve to partition the elements...
void set_sfc_type(std::string sfc_type)
Sets the type of space-filling curve to use.
