SmartDO was applied
on real-world industrial design since 1992. It has been applied on the following
field
- Life prolonging of semi-conductor component
- Keratotomy Surgeries
- Civil structure and resident roof optimization (sizing,
shaping and topology)
- Life prolonging and weight reduction
for the components of gas turbine engines
- Enhancement for the performance of the fluid power system
- Weight reduction and strength increase of the nuclear heavy-duty
lifting hook
- Performance optimization of the shock absorbing mechanism
- Weight reduction of the air cargo flood
deck
- Performance optimization of the thermoelectric
generator
- Weight reduction of the lower A-Arm
of the armored tank
- Performance curve optimization for the
keyboard rubber dome.
- Performance curve optimization for the
connectors
- Strength optimization of the circulation
water pump in power plant.
- Structural optimization for the wave
energy converter.
The Leader of Smart Global Optimization Technology. Capable
of Direct Global Search For Both Gradient-Based and GA-Based Methodology
|
SmartDO focuses
on the practical global optimization technology. Both Gradient-Based
NLP or the Genetic Algorithms solvers in SmartDO are capable of Direct
Global Search.
The world leading Response
Smoothing Technology in the Gradient-Based solver of SmartDO can eliminate
the numerical noise caused by meshing, discretization, and other
phenomena during numerical analysis. , Combined with the Direct
Global Search Technology, the Gradient-Based
NLP solver provide a more efficient and accurate way of getting
the optimum.
The Genetic Algorithms
can be used to solve problems not suitable for the gradient-based
solver. And the Gradient-Based NLP solver provide a more efficient
and accurate way of getting the optimum. These two algorithms together
make SmartDO a practical and powerful optimizer.
|
With Gradient-Based RCFDM, the Robust
Genetic Algorithms and the Smart Particle Swarm. Applicable on Wide-Ranging
Problems
|
With both
Gradient-Based NLP and the Genetic Algorithms, you can switch between
these two categories of solvers or use them simultaneously.
This allows the users apply SmartDO on different kinds of real-world
problems.
The Gradient-Based RCFDM
solver uses the following techniques to achieve Direct Global Search, including
- Combining Tunneling and Hill Climbing to jump out of local
minimum
- Automatic response smoothing on mesh discretization and other
numerical noise.
- Automatic recognition of active constraints. Much more efficient
and stable
- Smart Dynamic Search to automatically adjust search direction
and step size.
The Robust Genetic Algorithms in SmartDO is powered
by many unique technologies to achieve efficiency and stability,
including
- Adaptive Penalty Function
- Automatic Schema Representation
- Automatic Population and Generation Number Calculation
- Adaptive and Automatic Cross-Over Probability
Calculation
- Absolute Descent.
All the Direct Global Search Technology in our solver
make SmartDO much more powerful and efficient than other packages on the
market.
The Smart Particle Swarm is a solver
with the benefits of both the Robust Genetic Algorithms and the Gradient-Based
approaches. While it starts the global optimization with multiple initial
design points, each individual design (which is called the "particle")
will exchange design history and "experience" with each other. What is
unique is, the calculation of the new search direction is a semi-gradient
approach.

No Theoretical Restriction on Number of Design Variables and/or
Constraints. Can Start From and Infeasible Design Point
For all the solvers in SmartDO, there is no theoretical and/or
coding restriction on the number of design variables and/or constraints. Powered
by its Direct Global Search techniques, SmartDO can start from an infeasible
design point, pushing the design into the feasible domain first, and then
proceed with optimization.
Concurrent Sizing, Shaping and Topology Optimization
|
Because there
are various types of design variables available in the Robust Genetic
Algorithms of SmartDO, the users can perform Concurrent
Sizing, Shaping and Topology Optimization in a stable and efficient
fashion.
The problem of Concurrent
Sizing, Shaping and Topology Optimization usually requires intensive
numerical effort. With the Smart Heuristic
Search Technology, SmartDO is able to avoid unnecessary calculation
and save considerable amount of computational time.

Open Architecture, User Programmable with Tcl/Tk
SmartDO uses Tcl/Tk as
its basic platform, which makes its architecture highly open and user programmable.
In today's competitive environment, the user programmable features allow
you to differentiable with your competitor, and accumulate your know-how
and experience in the script. With Tcl/Tk, the user can import add-on packages,
and also develop GUI, Graphics and plotting in SmartDO
Error Tolerant. Restart From The Interrupted Point
SmartDO is highly error
tolerant. The user can usually restart from where the calculation is interrupted,
in case of unpredicted incident or system shutdown.
SmartDO can also ignore the noise or nonconvergence during the CAE analysis
without human judgment.
Engineering Lifecycle Integration
The open architecture
of Tcl/Tk in SmartDO make the Engineering CAx Lifecycle Integration
possible. Through the building of CAx Cycle Integration, SmartDO can
reduce the human error during the CAx design cycle, and further parameterize,
automate and optimize the design process.

Control Panel GUI
|
Control Panel acts as
the the optimization process integrator. With the tasks and connections
layout as graphical flowchart on the panel, the user can easily understand
and control the design optimization process. Also, all actions and settings
are just few clicks away. The Control Panel can be used to
- Overlook the layout
of the design optimization process
- Set up controlling parameters
- Integrate with external
programs
- Test the integrated
engineering cycle
- execute optimization
- Review the optimization
result
|
SmartScripting GUI
|
SmartScripting is a
GUI for generating Tcl/Tk script automatically. The user can access the programmable
feature of SmartDO by answering questions in the SmartScripting GUI, and
SmartScripting will generate Tcl/Tk scripts accurately with convenience. With
SmartScripting, programming with SmartDO is easy and efficient. SmartScripting
now has many frequently used template built in, for example
- Substitute the design
variable
- Call an external program
- Delete files
- Open/close a file to
read
- Search for a string
and react
- Retrieve values from
a string
- Mathematical expression
