27 Description
28  Minmod gradient limiter
29 
30  This is the default gradient limiter which clips the gradient to remove cell
31  to face extrapolation unboundedness. It corresponds to the original
32  cellLimitedGrad implementation before the addition of run-time select-able
33  limiter functions.
34 
35  Example:
36  \verbatim
37  gradSchemes
38  {
39  default Gauss linear;
40  limited cellLimited Gauss linear 1;
41  }
42  \endverbatim
