Geometric operations are necessary to generate a coherent solid model from the conceptual layout. Modern CAD systems are highly productive tools for concept embodiment, detailing, and preproduction engineering. Systems with fully integrated behaviour modelling and simulation functionality provide the engineer with tools capable of supporting a number of engineering steps in all life-cycle phases of a product. The simplified operations developed at QUB FEM facilitate rapid and full re-use of idealised conceptual model details to create full solid CAD and analysis models. They provide functionality for adding complexity to simple models are dimensional addition, detail insertion and symmetry addition, all of which have been demonstrated in the examples shown.
The integration of analysis modelling into CAD systems has enormous potential benefits. A huge range of geometry construction and modification tools are available, whilst access to the feature tree used to create the model means that optimisation studies can modify design geometry directly rather than the finite element mesh. Thus analysis-driven design is facilitated.
