OPENFOAM Boundary Conditions

desanga · April 9, 2014, 10:29

Hi Foamers,

I'm new to openfoam and cfd. im doing a research about rotating disk in still fluid (karman rotating disk). in order to do that i need to impose some boundary conditions. i want to impose velocity derivatives at the inlet (eg : dw/dz=0) see pic for full list of boundary conditions. how i'm going to implement this inside openfoam.

Thanks in advanced

Dear Desanga,
try the zeroGradient for velocities BC in 0-folder.

Code:

PATCHNAME
    {
        type            zeroGradient;
    }

Best regards
Julian
