We are looking for information regarding Structural Engineering Optimization Tools as applied to Derricks, Slef Supported and Guyed Stacks and may be Pressure Vessels.
I think STAAD has an optimization module. NASTRAN does as well. I had a friend who worked for an Auto maker and they use NASTRAN a lot. He told me once that they saved about 6 pounds on the car frame through optimization. I ridiculed the number but soon realized that is tremendous for a car. Think of the gas mileage that would be saved.
