1. Workshop 4Goal-Driven Optimization DesignXplorer

2. Workshop 4 Minimum web Maximum web • Goal • Investigate the deflection and mass for model shown here as the load and the geometry are varied. • The goal is to minimize mass and deflection with mass as the most important consideration. • Model Description • Constrains and Load are shown on the picture.
