Cuts (splits) cells.
Description of cut is given as a loop of 'cuts' per cell (see cellCuts). setRefinement() takes this cut description and inserts the necessary topoActions (add points/faces/cells) into the polyTopoChange.
Stores added cells/faces/points.
Cut description gives orientation to cut by calculating 'anchorPoints'. The side of the cell that contains the anchorPoints is the master cell. Likewise the cells' edges will have the split added as a duplicate of the master (anchor) point. Think of it as the cell with the anchor points at the bottom. Add a face at the bottom to split the cell and then sweep this face up to be through the middle of the cell (inflation).
+-------+ | + | + | + | + | + | + | + +-------+ anchor anchor
+-------+ | + | + | + <- addedCell | + | + | + +-------+ <- splitFace +-------+ <- original cell anchor anchor
+-------+ | + | + <- addedCell | + +-------+ <- splitFace | + | + <- original cell | + +-------+ anchor anchor
Anyway this was the original idea. Inflation was meant to handle conservative properties distribution without interpolation. (just face sweeping through space). But problem was that only if the introduced splitface was exactly the same shape as bottom face (so same 2D topo or perfectly flat) the volume between them was 0.
This meshCutting still uses anchorPoints though:
