ANSYS DesignXplorer Design of Experiments
With little more effort than for a single run, you can use DesignXplorer to
create a DOE and run many variations.

Goal-Driven Optimization
Use an optimization algorithm or screening to understand
tradeoffs or discover optimal design candidates!
© 2011 ANSYS, Inc. September 14, 2011
19
Robustness Evaluation
Input parameters have variation!
Output parameters vary also!
Understand how your performance will vary
with your design tolerances?
Make sure your design is robust!
Six Sigma, TQM
Predict how many parts will
likely fail?
Understand which inputs require the greatest control?

Engineers face numerous obstacles that prevent them from using optimization fully
Our plans are largely based on removing those obstacles so our customers can get more out of simulation

Many ways to reduce the time requirements
• Speedup of individual components
– Geometry import, meshing, solve, etc.
• Speedup between design points
– “DOE Sorting” at 14.0
– Mesh morphing
• Reduce the number of design points required
– Improved Sparse Grid DOE at 14.0
– New Auto-Kriging at 14.0
– New KMOGA adaptive optimization coming at 14.5
– Researching ways to use Adjoint information or ROM to dramatically reduce the number of solves required
• HPC to distribute the solve
– New distributed design point solve with RSM at 14.0
Running all those design points takes too long!

~1/3rd of Engineers would prefer to use their own algorithms for Optimization
Algorithms R15
• Opening up our Optimization Platform (R15)
– Matlab optimization toolbox
– API for customized optimization algorithms
– Flexible process with custom cost functions and convergence criteria
• This flexibility will be in addition to our “out of the box” functionality designed to please the other 2/3rds.
