4 symmetry BC in a cuboid
 

Hi!

Is it possible, to have 4 symmetry BC in a volume? It is a cuboid, with one inlet, an opposide outlet and the other 4 sides are symmetry BC (two of them shared by the geometry).

The geometry is 1/4 part of a cylinder that is part of a big bundle of parallel cylinders. I want to modell the axial flow between the cylinders.

So i have two symmetry BC displaying the symmetry of the cylinder, and two other for the symmetry in the boundle.

I think, I can not apply periodic BC.

Any help is highly appreciated!
