	Crashworthiness Optimization SmartDO can perform practical crashworthiness optimization with reasonable computational effort. For details, please click here.

	Comparison with SmartDO and Other Package The revolutionary technology in SmartDO makes it more robust , reliable and stabler.This example was from the final project of the graduate from National Chiao Tung University in Taiwan. The project was based on SmartDO and another package, and comparing their results. The results show that SmartDO is obviously superior to another package.

	Structural and CFD Global Optimization, and Comparison with SmartDO and Traditional Algorithms The Response Smoothing Technolgy in SmartDO allows the searching of global optimum with gradient-based NLP approach. The gradient-based NLP approach is usually more reliable, accurate and efficient. SmartDO has been used in real-world industiral structural and CFD Global Optimization. The experience has shown that SmartDO is superior to the traditional approach. This application has been also publised int he following paper. S-Y. Chen, 2007, Gradient-Based Structural and CFD Global Shape Optimization with SmartDO and the Response Smoothing Technology, Proceedings of the 7th World Congresses of Structural and Multidisciplinary Optimization (WCSMO7), COEX Seoul, 21 May – 25 May 2007, Korea

	Roof Structure Design Automation System Skeleton structural is used in many different structural systems, like airplane, automobile, ship and buildings. Its design consideration is generally different in the following ways. The cross-sections need to be selected from the stock Connection is usally by bolts or rivet, which is labor intensive. Manufacturing cost needs to be considered. Reliability and strength of structures need to be verified against design code. In order to acheive real efficient design, simultenious Sizing, Shaping and Topology optimization must be involved. For practical application purpose, the system must be efficient and stable, and a "push-botton" automation is desired. Conventional try-and-error approach is no longer acceptable. After evaluation, the traditional Nonlinear Programming and Homogenization Method is not applicable. Only the Robust Genetic Algorithms (RGA) inside the SmartDO core engine can satisfy the requirement of the customer. The system was customized by FEA-Opt Technology and is truely a push-botton design automation system. Currently, there is no other company can achieve such result. Several Papers have been published for this application. Please see here.

	Turbine Rotor Disk Design Optimization System Turbine rotor disk endures high temperature, pressure and centrifugal under the operation condition. The material is usally push to its limit, and accurate analysis is necessary. The challenge is how to design a rotor of long life yet still has very light weight. Also, the integration of CAD and CAE frequently produce "numerical noise", which makes numerical optimization difficult, if not impossible The unique Response Smoothing Technology with Conjugate Feasible Direction Method (CFDM) inside SmartDO can easily overcome the numerical noise mentioned above, and successful integrating numerical design optimization into the CAD/CAE work flow. The result is significant. The system is frequently able to produce innovative design which achieve optimal goal.

	The Ejector Mixer Automatic Design Optimization System The Ejector Mixer is the essential facilities for almost all the chemical manufactory. Its efficiency directly impact the quality, cost and turn over of a company. Currently, the performance prediction of ejector in the industry is usually still emperical. And the design heavily depends on try and error. Based on our industrial experience and CFD capability, FEA-Opt Technolog isolates the key parameters rapidly, integrating CFD and design optimization system, and successfully build up the design automation system for the customer. Like other systems we have built for our customers, it is also a push-button solution. The system was proved to be stable, reliable and innovative. In one realistic design example, the system was able to increase 50% of suction ratio and 25% of suction flow rate, with the same overall length and maximum diameter.
