24 Class
25  Foam::wallDist
26 
27 Description
28  Interface to run-time selectable methods to calculate the distance-to-wall
29  and normal-to-wall fields.
30 
31  Example of the wallDist specification in fvSchemes:
32  \verbatim
33  wallDist
34  {
35  method meshWave;
36 
37  // Optional entry enabling the calculation
38  // of the normal-to-wall field
39  nRequired false;
40  }
41  \endverbatim
