static |
Specialised method to compute a parallel partitioning of a given mesh (called by ComputeMeshPartitioning, based on the value of mMetisPartitioning)
rMesh | is the original mesh (so that we can set the DistributedVectorFactory up |
rNodesOwned | is an empty set to be filled with the indices of nodes owned by this process |

Specialised method to compute the partition of a mesh based on geometric partitioning
rMeshReader | is the reader pointing to the mesh to be read in and partitioned |
rNodePermutation | is the vector to be filled with node permutation information. |
rNodesOwned | is an empty set to be filled with the indices of nodes owned by this process |
rProcessorsOffset | a vector of length NumProcs to be filled with the index of the lowest indexed node owned by each process |
pRegion | the local region owned by this process. |
