Optimization provides an elegant blend of theory and applications. The theory uses elements beginning with elementary calculus and basic linear algebra and continues with functional and convex analysis. Applications of optimization involve science, engineering, economics, and industry. The wide and growing use of optimization make it essential for students and practitioners in every branch of science and technology. This book presents how to use Siemens Solid Edge ST3 software package, NX Nastran (7) solver to Optimize Engineering components. Some components of a small tricycle truck with tipping mechanism were chosen to illustrate the optimization process.
