Class
Foam::fv::cellLimitedGrad
Description
cellLimitedGrad gradient scheme applied to a runTime selected base gradient
scheme.
The scalar limiter based on limiting the extrapolated face values
between the maximum and minumum cell and cell neighbour values and is
applied to all components of the gradient.
