Detailed Description

template<class Type>
class Foam::fv::cellMDLimitedGrad< Type >

cellMDLimitedGrad gradient scheme applied to a runTime selected base gradient scheme.

The scalar limiter based on limiting the extrapolated face values between the maximum and minimum cell and cell neighbour values and is applied to the gradient in each face direction separately.
