DesignXplorer in Workbench (It’s built for SDPD)


13

ANSYS DesignXplorer

DesignXplorer systems are found under the Parameter set bar…

• Low cost & easy to use!

• It drives Workbench

• Improves the ROI!


14

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.


15

Correlation Matrix

Understand how your parameters are correlated/influenced by other parameters!


16

Sensitivity

Understand which parameters your

design is most sensitive to!


17

Response Surface

Understand the sensitivities of the output parameters (results) wrt

the input parameters. 3D Response

2D Slices Response


18

Goal-Driven Optimization

Use an optimization algorithm or screening to understand

tradeoffs or discover optimal design candidates!


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?


20

ANSYS DesignXplorer Initial vs. Optimized Design

Output Initial Design Optimized

Tt Ratio 1.116 1.126

pt Ratio 1.674 1.709

η [%] 71.65 76.25

Power [MW] 1.208 1.268

Engineers can easily appreciate the value of

understanding.

DesignXplorer Vision

(It’s built for SDPD)


22

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

Remove the Road Blocks

Do you use optimization software?

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.
