Emulating symmetryPlane boundary conditions

I have a case in which I want to make use of the symmetries of the geometry, but in my model I have some antisymmetric fields for which I need a mixed BC with different valueFraction for normal and tangential directions. Now OpenFOAM does not allow to use anything else than a symmetryPlane BC for symmetryPlane patch types.
Is there any way around this? I could remove the check in the code of course, but is this reasonable, or could it cause other problems? As an alternative approach, what are the correct boundary conditions for a symmetry without using symmetryPlane patchType and BC? p: zeroGradient U: slip T: zeroGradient Is this correct? |

Hi Chriss85,
I think that the conditions that you are using reproduce the symmetry condition for these variables. To be completely sure you may perform two simulations one using the symmetryPlane condition and another using the modified ones, and then compare the results. They should be equal. Best Regards, Paulo |
