Detailed Description

Sends/receives parts of mesh+fvfields to neighbouring processors. Used in load balancing.

Input is per local cell the processor it should move to. Moves meshes and volFields/surfaceFields and returns map which can be used to distribute other.

Notes:

  • does not handle cyclics. Will probably handle separated proc patches.
  • if all cells move off processor also all its processor patches will get deleted so comms might be screwed up (since e.g. globalMeshData expects procPatches on all)
  • initial mesh has to have procPatches last and all normal patches common to all processors and in the same order. This is checked.
  • faces are matched topologically but points on the faces are not. So expect problems -on separated patches (cyclics?) -on zero sized processor edges.
