Converting a Converging-Diverging Nozzle to 2D
 

Hello,

I am relatively new to Star-CCM+ and I am currently trying to run a design in 2-D as opposed to 3-D. I created a geometry of a converging-diverging nozzle where the channel is in the Z-direction. It continuously keeps saying that there are no boundaries in the Z = 0 plane, when the inlet and outlet of the nozzle clearly lies on the Z = 0 plane. Thank you for any information.

make sure creat CAD on x-y plane，and make sure begin from (0,0) point
