refinementHistory Class Reference

All refinement history. Used in unrefinement. More...

#include <dynamicMesh/refinementHistory.H>

Detailed Description

All refinement history. Used in unrefinement.

- visibleCells: valid for the current mesh and contains per cell -1 (cell unrefined) or an index into splitCells_.

  • splitCells: for every split contains the parent (also index into splitCells) and optionally a subsplit as 8 indices into splitCells. Note that the numbers in splitCells are not cell labels, they are purely indices into splitCells.

E.g. 2 cells, cell 1 gets refined so end up with 9 cells: 

// splitCells
9
(
-1 (1 2 3 4 5 6 7 8)
0 0()
0 0()
0 0()
0 0()
0 0()
0 0()
0 0()
0 0()
)

// visibleCells
9(-1 1 2 3 4 5 6 7 8)

So cell0 (visibleCells=-1) is unrefined. Cells 1-8 have all valid splitCells entries which are:

  • parent:0
  • subsplits:0()

The parent 0 refers back to the splitcell entries.
