This class separates the mesh into distinct unconnected regions, each of which is then given a label according to globalNumbering().
Say 6 cells, 3 processors, with single baffle on proc1.
baffle | +—+—+—+—+—+—+ | | | | | | | +—+—+—+—+—+—+ proc0 | proc1 | proc2
1: determine local regions (uncoupled)
+—+—+—+—+—+—+ | 0 | 0 | 0 | 1 | 0 | 0 | +—+—+—+—+—+—+ proc0 | proc1 | proc2
2: make global
+—+—+—+—+—+—+ | 0 | 0 | 1 | 2 | 3 | 3 | +—+—+—+—+—+—+ proc0 | proc1 | proc2
3: merge connected across procs
+—+—+—+—+—+—+ | 0 | 0 | 0 | 2 | 2 | 2 | +—+—+—+—+—+—+ proc0 | proc1 | proc2
4. determine locally owner regions. determine compact numbering for the local regions and send these to all processors that need them:
proc0 uses regions:
So proc1 needs to get the compact number for region 0 from proc0 and proc2 needs to get the compact number for region 2 from proc1:
+—+—+—+—+—+—+ | 0 | 0 | 0 | 1 | 1 | 1 | +—+—+—+—+—+—+ proc0 | proc1 | proc2
Can optionally keep all regions local to the processor.
