◆ lduPrimitiveMesh() [3/4]

lduPrimitiveMesh ( const label  comm,
const labelList procAgglomMap,
const labelList procIDs,
const lduMesh myMesh,
const PtrList< lduPrimitiveMesh > &  otherMeshes,
labelList cellOffsets,
labelList faceOffsets,
labelListList faceMap,
labelListList boundaryMap,
labelListListList boundaryFaceMap 
)

Construct by combining multiple meshes. The meshes come from.

processors procIDs: procIDs[0] : local processor (myMesh) procIDs[i] : processor where otherMeshes[i-1] comes from procAgglomMap : for every processor which processor it agglomerates onto. The new processor numbers are in compact numbering (so ranks in communicator comm), i.e. similar to cell-restrict-addressing. We need this information to be able to map inter-processor interfaces cellOffsets : for every processor the offset it gets in the mesh faceMap : for every processor, for every face, the destination face. Negative for flipped faces. boundaryMap : for every processor, for every patch, -1 or the new patch index in the mesh. boundaryFaceMap : for every processor, for every patch, for every patch face:

  • the new internal face (if boundaryMap=-1)
  • the new patch face (if boundaryMap>=0) Faces becoming internal are negative for flipped faces.
