Can someone explain what boundaries conditions you can use on the cut face of the 90 degree quadrant shown in figure 2 (second picture) to simulate the vessels geometrical symmetry. Screenshots of how to apply them would be appreciated.

Figure 2 shows a 90 degree quadrant of the top half of the air receiver you are to optimize. The shell and header thickness could be assumed to be the same. The header is to be of hemispherical construction and welded to the shell cylinder. The geometry of the top half of the vessel is a mirror image of the bottom half. The vessel geometry therefore is predominantly symmetric apart from the single air outlet pipe in the top half of the vessel and the single air inlet pipe in the bottom half. You have been advised by the senior design engineer to only model a 90 degree quadrant of the vessel (as in Figure 2) using appropriate boundary conditions on the 'cut faces' of the air receiver to simulate the vessels inherent geometrical symmetry. A non-linear finite element analysis can be time consuming and therefore costly to the company.
