• During the computer-aided development of a product, the primary task of design engineers is to create a detailed electronic description of this product.

• At certain stages of the product development cycle, this design representation is used to drive a series of engineering analyses that validate the design

• In order to perform these analyses, the design representation must be first idealized and transformed into some form that admits mathematical evaluation.

• This slide illustrates this design-idealize-analyze sequence with an example from thermomechanical analysis of printed wiring assemblies.
