Detailed Description

Calculates points shared by more than two processor patches or cyclic patches.

Is used in globalMeshData. (this info is needed for point/edge communication where processor swaps are not enough to exchange data)

Works purely topological and using local communication only. Needs:

• domain to be one single domain (i.e. all faces can be reached through face-cell walk).
• patch face ordering to be ok
• f[0] ordering on patch faces to be ok.

Works by constructing equivalence lists for all the points on processor patches. These list are in globalIndexAndTransform numbering E.g.

      ((7 93)(4 731)(3 114))

means point 93 on proc7 is connected to point 731 on proc4 and 114 on proc3. It then assigns the lowest numbered processor to be the local 'master' and constructs a mapDistribute to send all data to this master.

Algorithm:

• get meshPoints of all my points on processor patches and initialize equivalence lists to this. loop
• send to all neighbours in relative form:
  • patchFace
  • index in face
• receive and convert into meshPoints. Add to to my equivalence lists.
• mark meshPoints for which information changed.
• send data for these meshPoints again endloop until nothing changes

At this point one will have complete point-point connectivity for all points on processor patches. Now (optionally) remove point equivalences of size 2. These are just normal points shared between two neighbouring procPatches.

Note: the data held is either mesh point labels (construct from mesh only) or patch point labels (construct from mesh and patch).
