Traditional: Cylinder with spherical caps
Extends from TRANSFORM.Fluid.Volumes.ClosureModels.Geometry.DrumTypes.PartialDrumType.
Information
A traditional pressurizer geometry with two spherical caps and a cylindrical middle body.
The surface area associated with the wall is calculated as the outer surface of the three regions. In other words,
if the radii are not the same, the calculation does not calculate the differences into the surface area calculation although
it is factored into the volume and therefore the liquid level calculation.
