Rodin::Geometry::Partitioner class
#include <Rodin/Geometry/MeshPartitioner.h>

Abstract base class for mesh partitioning strategies.

A Partitioner divides mesh polytopes into disjoint partitions, which is useful for load balancing, parallel processing, and domain decomposition methods. Each polytope is assigned to exactly one partition.

Derived classes

class BalancedCompactPartitioner: Partitioner that creates balanced, spatially compact partitions.
class GreedyPartitioner: Partitioner using a greedy algorithm.

Constructors, destructors, conversion operators

Partitioner() defaulted: Default constructor.
~Partitioner() defaulted virtual: Virtual destructor.

Public functions

auto getMesh() const -> const Mesh<Context::Local>& pure virtual: Gets the mesh being partitioned.
void partition(size_t numPartitions, size_t d) pure virtual: Performs the partitioning of mesh polytopes.
auto getPartition(Index index) const -> size_t pure virtual: Gets the partition index for a given polytope.
auto operator[](Index index) const -> size_t: Operator overload for getting partition index.
auto getCount() const -> size_t pure virtual: Gets the total number of partitions.

Function documentation

const Mesh<Context::Local>& Rodin::Geometry::Partitioner::getMesh() const pure virtual

Gets the mesh being partitioned.

Returns	Reference to the mesh

void Rodin::Geometry::Partitioner::partition(size_t numPartitions, size_t d) pure virtual

Performs the partitioning of mesh polytopes.

Parameters
numPartitions in	Number of partitions to create
d in	Dimension of polytopes to partition

Divides the polytopes of dimension d into numPartitions disjoint partitions according to the partitioning strategy.

size_t Rodin::Geometry::Partitioner::getPartition(Index index) const pure virtual

Gets the partition index for a given polytope.

Parameters
index in	Index of the polytope
Returns	Partition number assigned to the polytope

size_t Rodin::Geometry::Partitioner::operator[](Index index) const

Operator overload for getting partition index.

Parameters
index in	Index of the polytope
Returns	Partition number assigned to the polytope

size_t Rodin::Geometry::Partitioner::getCount() const pure virtual

Gets the total number of partitions.

Returns	Number of partitions created
