Detailed Description

Post-processing mesh subset tool. Given the original mesh and the list of selected cells, it creates the mesh consisting only of the desired cells, with the mapping list for points, faces, and cells.

Puts all exposed internal faces into either

  • a user supplied patch
  • a newly created patch "oldInternalFaces"
  • setCellSubset is for small subsets. Uses Maps to minimise memory.
  • setLargeCellSubset is for largish subsets (>10% of mesh). Uses labelLists instead.
  • setLargeCellSubset does coupled patch subsetting as well. If it detects a face on a coupled patch 'losing' its neighbour it will move the face into the oldInternalFaces patch.
  • if a user supplied patch is used it is up to the destination patchField to handle exposed internal faces (mapping from face -1). If not provided the default is to assign the internalField. All the basic patch field types (e.g. fixedValue) will give a warning and preferably derived patch field types should be used that know how to handle exposed faces (e.g. use uniformFixedValue instead of fixedValue)

Set the subset. Create "oldInternalFaces" patch for exposed.

Set the subset from all cells with region == currentRegion.

Create "oldInternalFaces" patch for exposed internal faces (patchID==-1) or use supplied patch. Handles coupled patches by if necessary making coupled patch face part of patchID (so uncoupled)
