Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
class ParallelTetrahedralMesh< ELEMENT_DIM, SPACE_DIM >

Parallel implementation of a mesh Nodes are distributed such that each process has A set of nodes (possibly reordered) with contiguous global indices A local copy of all the elements supporting those nodes A local copy of ghost/halo nodes which are all the nodes used in the supporting elements, but not owned outright.
