Comparison with SmartDO
and Other Package
The revolutionary
technology in SmartDO makes it more robust , reliable and stable.
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 Technology 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 industrial structural and CFD
Global Optimization.
The experience has shown that SmartDO is superior to the traditional
approach. This application has been also published in he following
paper.

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 usually 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
achieve efficient design, simultaneous Sizing, Shaping and Topology
optimization must be involved. For practical application purpose,
the system must be efficient and stable, and a "push-button" 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 truly a push-button
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 usually 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 empirical. And the design heavily
depends on try and error.
Based on our industrial experience and CFD capability,
FEA-Opt Technology 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.
