hello, does anyone knows how to do cyclic/periodic boundary conditions in cfx, or has a reference to a similar subject?

for example :

there are 2 identical bodies in a tunnel, is it possible to define that the flow in section 1 will be identical to the flow in section 2?

This is fully supported in CFX 12, have a read of the documentation. In older versions of CFX I think you had to do this with a momentum source.
