I would like to save computation time by using an axisymmetric 2D computational domain instead of a 1/4 pie shaped 3D computational domain. Seems like there should be a way to do this but I'm not seeing it, the only choices are 3D, and 2D with symmetry but no axial symmetry as an option.

A screenshot of my geometry is attached (sectioned). It is a valve seat simulation, flow is from top to bottom. The valve seat itself is a tight clearance which requires a small mesh and results in long computation time.

Thanks
