	)		const

Given valid mesh and current cell level and proposed.

cells to refine calculate any clashes (due to 2:1) and return ok list of cells to refine. Either adds cells to refine to set (maxSet = true) or removes cells to refine (maxSet = false)

		const labelList &	cellsToRefine,

		const label	maxPointDiff,
		const labelList &	pointsToCheck
	)		const

Like consistentRefinement but slower:

specify number of cells between consecutive refinement levels (consistentRefinement equivalent to 1)

specify max level difference between point-connected cells. (-1 to disable) Note that with normal 2:1 limitation (maxFaceDiff=1) there can be 8:1 size difference across point connected cells so maxPointDiff allows you to make that less. cellsToRefine : cells we're thinking about refining. It will extend this set. All refinement levels will be at least maxFaceDiff layers thick. facesToCheck : additional faces where to implement the maxFaceDiff thickness (usually only boundary faces)

Foam::labelList consistentSlowRefinement2	(	const label	maxFaceDiff,

Like consistentSlowRefinement but uses different meshWave.

(proper distance instead of toplogical count). No point checks yet.

Foam::labelListList setRefinement	(	const labelList &	cells,
		polyTopoChange &	meshMod
	)

Insert refinement. All selected cells will be split into 8.

Returns per element in cells the 8 cells they were split into. Guarantees that the 0th element is the original cell label. Mapping: -split cells: 7 new ones get added from original -split faces: original gets modified; 3 new ones get added from original -added internal faces: added from original cell face(if that was internal) or created out-of-nothing (so will not get mapped!). Note: could make this inflate from point but that will allocate interpolation. -points added to split edge: added from edge start() -midpoints added: added from cellPoints[0].
