Detailed Description

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

A second-order gradient scheme using face-interpolation, Gauss' theorem and iterative skew correction.

Usage

Minimal example by using system/fvSchemes:

gradSchemes
{
    grad(<term>)   iterativeGauss <interpolation scheme> <number of iters>;
}

and by using system/fvSolution:

relaxationFactors
{
    fields
    {
        grad(<term>)    <relaxation factor>;
    }
}
