lduPrimitiveMesh ( const label  nCells,
labelList l,
labelList u,
const label  comm,
bool  reUse 
)

Construct from components but without interfaces. Add interfaces.

lduPrimitiveMesh ( const label  nCells,
labelList l,
labelList u,
PtrList< const lduInterface > &  primitiveInterfaces,
const lduSchedule ps,

Construct from components and re-use storage.

lduPrimitiveMesh ( const label  comm,

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.
