Checkerboarding topology optimization
WebSections in this chapter detail speci c methods used to handle optimization of problems with many minima and problems with the numerical instability known as checkerboarding, both of which can occur in topology optimization. The method is then applied to the optimization of a nanocomposite beam cross-section in Chapter 4. WebThis checkerboarding is generally due to mathematical instability, commonly observed solution of minimum compliance problems. If checkerboarding problem is controlled in an efficient way we can obtain more accurate and highly optimized results in Topology Optimization. This paper reviews the various available checkerboarding control …
