the ug namespace
static bool PartitionDomain_Bisection(TDomain &domain, PartitionMap &partitionMap, int firstAxisToCut)
partitions a domain by repeatedly cutting it along the different axis
static bool PartitionDomain_MetisKWay(TDomain &domain, PartitionMap &partitionMap, int numPartitions, size_t baseLevel=0, int hWeight=1, int vWeight=1)
partitions a domain by using graph-based partitioning by METIS
static bool PartitionDomain_LevelBased(TDomain &domain, PartitionMap &partitionMap, int numPartitions, size_t level)
Partitions a domain based on the elements of one level.
static bool PartitionDomain_RegularGrid(TDomain &domain, PartitionMap &partitionMap, int numCellsX, int numCellsY, int numCellsZ, bool surfaceOnly)
partitions a domain by sorting all elements into a regular grid
static bool DistributeDomain(TDomain &domainOut, PartitionMap &partitionMap, bool createVerticalInterfaces)
distributes a already distributed domain onto the specified processes
