There are 3 typical development processes:

1. Traditional design-build-test process
This is very typical process before CAE technologies are well adapted into design process. Almost no CAE simulation is down in traditional development process so the building time and test is very long, cost is very high. Also because of TTM limit, many concepts can not be validated before product lunch, which causes many reliability and quality issues.

2. Digital Engineering process
Many companys are using or building this process. With the development of CAE technologies, before the prototypes are built, simulation is used to validate some of the product targets.

In a certain level, digital engineering process reduct the TTM and problems after product lunch. But this process does not seperate concept design with detail design completely. The origincal geometry is very detailed and complicated, which makes the changes very difficult. Also most of the simulations are 3D analysis at component level, which can not solve the system issue at very beginning. It is still down to top design.

3. SE/ALD process
SE/ALD is a top to down design process. It separates the concept design with detail design totally, which shift the traditional test verification to upfront system modeling simulation. By using product target setting and cascading, system models are created at different level and validated by using baseline or competitors’ product. Those models then can be used to do design optimization to achieve targets before detail design starts.

Typical SEALD project process

• Baseline analysis
  1. Baseline system modeling (1D or 3D)
  2. Correlate with test result
  3. Define key parameters and sensitive study
  4. Recommend design changes

• Design Improvements
  1. Execute design changes
  2. Finalized design that meets performance for final proto & test

• Reuse of modeling for future design
• Knowledge Transfer

What we offer

We will work with customer side by side to help customer establish System modeling and ALD process, at the same time, transfer the knowhow to customer to really help customer to be successful. During the project, what we offer are as below:

• Overall SEALD process transfer
• Detailed simulation modeling guidelines/coaching
• Test correlation planning
• Sensitive studies technologies
• Design optimization
• Software on-job training with real projects

For specific problem, the project will be measured by problem solved and for new product development, the project will be measured by the design targets are satisfied.

The philosophy of our consulting on SEALD is “Knowledge Transfer” to really help customer to be able to design their product independently after several projects working with us.

Benefits to Customers

Below is the comparison of SEALD with other 2 processes.


X axial is the development phases
Y axial is the number of problem solved.

By using SEALD process:

• Build up system models that could be reused in the future for new design
• Most of the problems are solved before detail design starts
• Development time are significantly reduced because of protos and test are replaced by simulation
• Development cost is much less
• By working with us, we will transfer simulation technologies to customers as well including structure & fatigue, hydraulic, heat/flow analysis, NVH etc.
