Step 4: Specify geometry
Because of the inherent symmetry of the model, we'll perform the analysis on a quarter of the volumes only. Recall that a=0 (i.e. angle between the planes in which radii R1 and R2 lie is zero). As a result, the upper and lower volume have the same orientation, when viewed from the top.
