Learn how to use SOLIDWORKS Simulation Xpress to validate part strength and performance in a virtual environment. This tutorial walks through a real-world example using a lug wrench, covering fixture setup, load application, material selection, and running stress analysis. See how to interpret results like factor of safety, Von Mises stress, and displacement, then generate reports or export findings. The video also demonstrates quick design optimisation to improve performance while minimising weight. Simulation Xpress offers an easy introduction to finite element analysis, helping designers reduce costs and accelerate development by avoiding unnecessary physical prototypes.
