31 Class
32  Foam::limitFuncs::LimitFuncs
33 
34 Description
35  Class to create NVD/TVD limited weighting-factors.
36 
37  The particular differencing scheme class is supplied as a template
38  argument, the weight function of which is called by the weight function
39  of this class for the internal faces as well as faces of coupled
40  patches (e.g. processor-processor patches). The weight function is
41  supplied the central-differencing weighting factor, the face-flux, the
42  cell and face gradients (from which the normalised variable
43  distribution may be created) and the cell centre distance.
44 
45  This code organisation is both neat and efficient, allowing for
46  convenient implementation of new schemes to run on parallelised cases.
