3 Agenda ANSYS DesignXplorer ANSYS Engineering Knowledge Manager (EKM) 3

4 Design Exploration and Robust Design at ANSYS 4

5 Optimization tools at ANSYS ANSYS DesignXplorer Unified Workbench solution ANSYS Fluent Has built-in morphing and optimization tools Has an adjoint solver ANSOFT Optimetrics ANSYS MAPDL DX VT And more Baseline Design Optimized Design 5

6 ANSYS DesignXplorer Integral with Workbench Parametric multiphysics modeling with automated updates Bi-directional CAD, RSM, scripting, reporting and more... 6

7 Optimization Partners ANSYS simulation software has been effectively used to drive innovation in concert with optimization partners MATLAB (Mathworks) ModeFrontier (Esteco) OptiSLang (Dynardo) RBF-Morph Sculptor (Optimal) Sigma Technology (IOSO) TOSCA (FE-DESIGN) Qfin (Qfinsoft) and more 7

8 EKM to manage it all ANSYS simulation software has been effectively used to drive innovation in concert with optimization partners MATLAB (Mathworks) ModeFrontier (Esteco) OptiSLang (Dynardo) RBF-Morph Sculptor (Optimal) Sigma Technology (IOSO) TOSCA (FE-DESIGN) Qfin (Qfinsoft) and more Regardless of which Optimization tool you are using, the ANSYS Engineering Knowledge Manager can help you manage the data! 8

9 Workbench Principles (It s built for SDPD) 9

10 ANSYS Workbench Schematic Workflow 10

11 Workbench Integrates ANSYS tools and solvers Parametric, persistent and scriptable environment 11

12 DesignXplorer in Workbench (It s built for SDPD) 12

13 ANSYS DesignXplorer DesignXplorer systems are found under the Parameter set bar Low cost & easy to use! It drives Workbench Improves the ROI! 13

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. 14

15 Correlation Matrix Understand how your parameters are correlated/influenced by other parameters! 15

16 Sensitivity Understand which parameters your design is most sensitive to! 16

17 Response Surface Understand the sensitivities of the output parameters (results) wrt the input parameters. 3D Response 2D Slices Response 17

18 Goal-Driven Optimization Use an optimization algorithm or screening to understand tradeoffs or discover optimal design candidates! 18

19 Robustness Evaluation Input parameters have variation! Make sure your design is robust! Six Sigma, TQM Output parameters vary also! Understand how your performance will vary with your design tolerances? Predict how many parts will likely fail? Understand which inputs require the greatest control? 19

20 ANSYS DesignXplorer Initial vs. Optimized Design Output Initial Design Optimized T t Ratio p t Ratio η [%] Power [MW] Engineers can easily appreciate the value of understanding. 20

21 DesignXplorer Vision (It s built for SDPD) 21

22 Remove the Road Blocks 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 Do you use optimization software? 41.9% 18.6% 21.8% Matlab 16% 22

23 Running all those design points takes too long! 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 Resolution w/ fewer points 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 R14 Dynamic convergence feedback 23

24 Algorithms R15 ~1/3 rd of Engineers would prefer to use their own algorithms for Optimization 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. 24

25 Thank You We have also created a DesignXplorer user group on Linked-In Search Groups for DesignXplorer to join. 25

26 Harness Simulation Knowledge with ANSYS Engineering Knowledge Manager 26

27 Engineering Knowledge Manager DATA MANAGEMENT File Repository Meta-Data Extraction Advanced Search Data Mining Report Generation PROCESS MANAGEMENT Automate Processes Manage Workflows Design Systems Notification Track Progress File & web servers Compute server Enterprise Access Web Enabled end user Application Portal Job Submission 27 ACCESS MANAGEMENT

28 Challenge Challenge Today Simulation Results Are Intellectual Property They Contain Know-how And Your Competitive Advantage. Results Are Often Stored In An Ad-hoc Manner File Servers Engineer s Desktops The Data Is Seldom Reused About 80% of simulation data is stored on local desktop storage drives. 29

29 Retain and Reuse Simulation Knowledge Best Practice Process: Multiple Distributed Users Can Access Projects, Run Parametric Evaluations Identify Best Solution All Major Data Types Supported By Search And Reporting Capabilities Store Both Work-in-progress And Final Archivable Simulation Data Differentiated Capabilities Data Search and Retrieval Multi-Location Collaboration Results Visualization Design Comparisons Lifecycle Management Access/Revision Control Meta Data Extraction Scalable Optimization Design Points & Optimization PLM Integration 30

30 Meta-Data Extraction Download Upload As a dedicated specialist in the field of simulation, ANSYS knows what types of data is most likely to be searched. (Large file > 50MB) boundary conditions, solver settings, material data, etc.. Geometry Results Simulation Meta-Data (Small file <10KB) Large files put in repository Meta-data copied to database EKM Database Meta-data information can be configured User defined meta-data can be added User s Machine 31

31 Multi-location Collaboration Connect to multiple EKM data sources. Access data on all through single search. 32
