Divergence on symmetryplane
 

Hello

Im simulating the suns impact on a camera, the geometry consist of a camera, house and sun protector. I get pretty reasonable values for the temperature everywhere except two small areas on the simmetry-plane. Ive tried to make a better mesh but it didnt help, Im using the DO radiation model together with the solar load model.

(The air inside the house and the surrounding air is hidden on the uploaded picture, but it´s included on the model)

Can anyone please give me some advice on how to fix this?

I see that the velocity vectors behave very strangely at one of the points of divergence, they have the opposite direction of the velocity vectors around it. see picture, the point is on the symmetry plane

Please help me!
