E.4.3 - Beam Revolved Solid

Example overview

Additional test cases not yet allocated to individual test case groups.

This example illustrates a beam with revolved solid geometry, based on an parametric I-Shape profile and corresponding material profile set usage definition. Figure E.A shows the resulting shape.
