Hello All,

I was doing the below tutorial,

\OpenFOAM_Tutorials\incompressible\pisoFoam\ras\ca vityCoupledU

now the problem is,
I dont understand at all why they have selected such schemes like Gauss limitedLinearV 1, Gauss limitedLinear 1, Gauss linear ?

I have gone through the User Guide already but unfortunatelly there is no absolute answers/explanation availabale for it ! (they have just printed a Table thats it !)

I tried searching back and fourth in the forums, but couldn't find it.

default none;
div(phi,U) Gauss limitedLinearV 1;
div(phi,k) Gauss limitedLinear 1;
div(phi,epsilon) Gauss limitedLinear 1;
div(phi,R) Gauss limitedLinear 1;
div(R) Gauss linear;
div(phi,nuTilda) Gauss limitedLinear 1;
div((nuEff*dev(T(grad(U))))) Gauss linear;

If I narrow down my question,

Can anyone please help me understanding how these schemes are selected for perticular parameters ?
It is driving me crazy as I don't know what they exactly mean and what they exactly makes difference.
