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 )

Member Function Documentation

◆ ClassName()

ClassName ( "removeCells" )

Runtime type information.

References mesh.

◆ getExposedFaces() [1/2]

Foam::labelList getExposedFaces ( const bitSet & removedCell) const

Get labels of faces exposed after cells removal.

These are

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

◆ getExposedFaces() [2/2]

Foam::labelList getExposedFaces ( const labelUList & cellsToRemove) const

Get labels of faces exposed after cells removal.

These are

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

◆ setRefinement() [1/2]

void setRefinement ( const bitSet & removedCell,
const labelUList & facesToExpose,
const labelUList & 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!
