Class
    Foam::zoltanRenumber
 
Description
    Use Zoltan for renumbering a case in parallel.
 
    Note: Zoltan methods do not support serial operation.
 
Usage
    To select the Zoltan Hilbert space filling curves renumber method add the
    following entries to renumberMeshDict:
 
        method          zoltan;
        libs            ("libzoltanRenumber.so");
