WebbShape optimization problems are usually solved numerically, by using iterative methods. That is, one starts with an initial guess for a shape, and then gradually evolves it, until it morphs into the optimal shape. Keeping track of the shape Example: Shape optimization as applied to building geometry. WebbSelection of design variables Shape optimization problems are often concerned with reducing stresses at a boundary by changing that boundary, However, if care is not exercised in the selection of the design variables, the accuracy of the finite element model can deteriorate as the optimization proceeds to the point where the results of the …
