Cyclic Boundary condition for flow around tubes
 

Hello,

i am trying to make an cyclic b.c. for my flow around tubes. I dont want to connect the inlet and outlet instead i want to connect the left and right sights so its like a bigger surface. I think it should be something in the fvOptions.... Any suggestions?
