Detailed Description

Given list of cells to remove insert all the topology changes.

Works in two passes:

• get faces that will become boundary faces
• given these faces and the patches they have to go into make the changes.

Constructor & Destructor Documentation

removeCells()

removeCells	(	const polyMesh &	mesh,
		const bool	syncPar = true
	)

Construct from mesh. syncPar: do parallel synchronization.

Definition at line 60 of file removeCells.C.

Member Function Documentation

uncount()

void uncount ( const labelList &  f, labelList &  nUsage  )

staticprivate

Decrease count of elements of f.

Definition at line 45 of file removeCells.C.

getExposedFaces()

Foam::labelList getExposedFaces

(

const labelList &

cellsToRemove

)

const

Get labels of exposed faces.

These are

• internal faces that become boundary faces
• coupled faces that become uncoupled (since one of the sides gets deleted)

setRefinement()

void setRefinement	(	const labelList &	cellsToRemove,
		const labelList &	facesToExpose,
		const labelList &	patchIDs,
		polyTopoChange &	meshMod
	)		const

Play commands into polyTopoChange to remove cells.

patchIDs is for every element in facesToExpose (see above) the patch it has to go into. This cannot be a coupled patch!
