nutkRoughWallFunction, going nuts
 
Hi Foamers,

I am trying to implement nutkRoughWallFunction in OpenFoam 2.1.1 (formerly also apparently known as nutRoughWallFunction). This is how I am using it to define my wall at the bottom of my model:

Code:

        ffminz
        {
            type nutkRoughWallFunction;
            Ks        0.2;
            Cs        0.5;
            value uniform 0.0;
        }

This is what OpenFOAM-2.1.1 is telling me about my wall function parameters:

Quote:

Reading "/home/admin1/run/wingNut/processor0/0/nut::boundaryField::ffminz" from line 43 to line 46
expected keyword 'uniform' or 'nonuniform', assuming deprecated Field format from Foam version 2.0.
It still works, but it seems OF doesn't like it. What is the correct syntax in >OF2.1 ?

Thanks

For anybody interested, the correct syntax (at least post 2.0) is the following:

Code:

        ffminz
        {
            type nutkRoughWallFunction;
            Ks        uniform 0.2; //Ks = 20Z0 to 30Z0
            Cs        uniform 0.5;
            value uniform 0.0;
        }

Thanks, that solution works in openfoam 2.3
