Class
    Foam::springRenumber
 
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;
