Detailed Description

Use spring analogy - attract neighbouring cells according to the distance of their cell indices.

Maximum jump of cell indices. Is fraction of number of cells maxCo 0.1;

Limit the amount of movement; the fraction maxCo gets decreased with every iteration. freezeFraction 0.9;

Maximum number of iterations maxIter 1000;

renumber() [1/3]

virtual labelList renumber ( const pointField &  ) const

inlinevirtual

Return the order in which cells need to be visited, i.e.

from ordered back to original cell label. This is only defined for geometric renumberMethods.

Reimplemented from renumberMethod.

Definition at line 100 of file springRenumber.H.

renumber() [2/3]

Foam::labelList renumber ( const polyMesh &  mesh, const pointField &  cc  ) const

virtual

Return the order in which cells need to be visited, i.e.

from ordered back to original cell label. Use the mesh connectivity (if needed)

Reimplemented from renumberMethod.

renumber() [3/3]

Foam::labelList renumber ( const labelListList &  cellCells, const pointField &  cc  ) const

virtual

Return the order in which cells need to be visited, i.e.

from ordered back to original cell label. The connectivity is equal to mesh.cellCells() except

• the connections are across coupled patches

Implements renumberMethod.
