Is this symmetric?

Do you think this case can be handled with a symmetry plane (see attached image) I tried it as a symmetric case with same mesh and everything else exactly the same. One of my UDS and Omega leads to divergency. I thought for a symmetric flow pattern I can use symmetry. Non symmetric case works fine.
