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 synchronisation.

Member Function Documentation

◆ ClassName()

ClassName ( "removeCells"  )

Runtime type information.

◆ 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!
