Single Simulation
Single Solve
Solves a single simulation with
only a single physics
Engineers are interested in
solution robustness, speed,
accuracy, ease of use and Doesnt account for
accuracy, ease of use and
engineering results
Doesnt account for
physics interactions
Virtual Prototyping typically requires looking
at multiple physics, This single physics
approach is often not enough.
-
Single Multiphysics Solve
Solves a single simulation
involving multiple physics
Engineers are still interested in
solution robustness, speed,
accuracy, ease of use and
engineering resultsDoesnt provide
direction for design engineering results
And the ease and power of the
physics coupling
direction for design
improvement
How can I improve performance?
Can I reduce weight or cost?
What is limiting performance?
Is this a robust design?

What If Study
?
??
User adjusts inputs and investigates
results
Builds on previous expectations,
adds requirement of easy and robust
parametric updates and comparative
reports
Solutions compared,
but design is not well
understood and no reports
understood and no
optimum is found
Need a more scientific and automated way to
decide which points to solve
Need a way to interpolate between these points
-
Design Exploration Scientific methods to explore the
design space fully
Allows user for: sensitivity and
correlation, DOE and response surface
technology, mesh morphing, charting
and reporting
For complex solutions, user can take
Response

Provides design
understanding, But .
Optimize a design with selected inputs and goals
For complex solutions, user can take
advantage of robust efficient &
affordable ANSYS distributed solver
Technologies.

Arriving at a set of Optimal
design solutions Optimization
Searches the design space for
optimal candidates, given user-
defined goals and priorities
Adds requirements for: advanced
optimization algorithms to
Solutions may be too
sensitive to input optimization algorithms to
efficiently search for candidates,
comparative reporting
Real-world inputs typically have some variation
and may require a more robust design goal
sensitive to input
variability
-
Taking the variation of inputs into account, and
seeking a design with a probabilistic goal
RDO => Min standard deviation of the results
Robust Design
Input
distribution
Output
distribution
RDO => Min standard deviation of the results
Six Sigma => Optimal design within a safe domain
In order to arrive at Robust design, User needs to
- Specify probabilistic parameters
- Use probabilistic optimization algorithms
Robust Design optimizes design variables to achieve a
particular probabilistic level such as Six Sigma, which
translates into 3.4 failures in one million parts.
