How to Create Spherical Geometry (New User)
 

Hello, I wish to model flow past a sphere by creating the geometry in Design Modeler found in Workbench (Fluent 12.0). I would like to create the simulation in 2D, but I don't understand how to represent my 2D circle as a sphere for the flow, since it could also represent a cylinder. How do I make this distinction? So far I've only created surfaces for simple geometries like plates and pipes.

Any advice is greatly appreciated, thanks in advance.
