Unresolved boundary condition: Water Tunnel Contraction

I am designing a contraction for a water tunnel. I have attached the model in the post.

I am running into the error: unresolved boundary condition at inlet flow boundary condition. Can someone please tell me what I am doing wrong?

I have meshed half the contraction and have assumed symmetry in x-axis for the other half. Is that ok?

My initial conditions are set to zero. Is that ok?

Sorry, I am fairly new to this. The tutorials and online help has got me this far, but now I am stuck.
