In this example the process of performing a topology optimization for a simple bridge structure will be illustrated. The objective is to minimize the mass of the bridge while keeping the deflection less than 1mm. This is a 7 parts tutorial that includes the following: 1. Geometry creation - simple bridge shape 2. Mesh the bridge geometry 3. Apply material properties 4. Apply Loads and constraints 5. Setup and Run the analysis 6. Postprocessing results 7. Animate the Topology optimization iterations
