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.

Example:

\verbatim
37
gradSchemes
38
{
39
default Gauss linear;
40
limited cellLimited Gauss linear 1;
41
}
42
\endverbatim
