24 Class
25  Foam::FaceCellWave
26 
27 Description
28  Wave propagation of information through grid. Every iteration
29  information goes through one layer of cells. Templated on information
30  that is transferred.
31 
32  Handles parallel and cyclics and non-parallel cyclics.
33 
34  Note: whether to propagate depends on the return value of Type::update
35  which returns true (i.e. propagate) if the value changes by more than a
36  certain tolerance.
37  This tolerance can be very strict for normal face-cell and parallel
38  cyclics (we use a value of 0.01 just to limit propagation of small changes)
39  but for non-parallel cyclics this tolerance can be critical and if chosen
40  too small can lead to non-convergence.
