Comparison Fluent-OF Schemes

Hi Foamers,

I would like to compare some results obtained with OpenFoam and Fluent and I have a doubt related to the interpolation Schemes.
In Fluent I am using the second discretization order upwind and I was wondering which scheme I should use in OpenFoam in order to get reliable results.
I would be pleased if someone could attach the fvSchemes file as I am quite new with OF.
Thanks in advance.

Hi,

I believe the following "divScheme" is quite the same as the scheme Fluent calls second order upwind:

Code:

divSchemes

{

    div(phi,U)               Gauss linearUpwindV cellLimited Gauss linear 1;

    div(phi,k)               Gauss linearUpwind cellLimited Gauss linear 1;

    div(phi,epsilon)      Gauss linearUpwind cellLimited Gauss linear 1;

    ...

}
