ANSYS design exploration tools lead the wayto Simulation-Driven Product Development.

Harness the power of parametric analysis to increase innovationand improve the return on your simulation investment.

R&D engineers often use simulation to assessthe performance of a single design a part ora system with set CAD dimensions, inputs andmaterial properties. Some have progressed tousing ANSYS Workbench to run simple,probing, what-if studies to improve design.

ANSYS DesignXplorer takes this to the next level,applying design-of-experiment (DOE) algorithmsto eciently and scientically factor the designspace. It also uses state-of-the-art responsesurface technology to interpolate the results.

Our parametric technology calculates correlationand sensitivity along with a host of other insightfulmetrics so you can more completely understandyour design space. Optimization algorithms helpto determine the best combination of parameters,and Six Sigma analysis ensures that your designis robust.

Simulation Driven Product Development

We developed the ANSYS Workbench environmentas a central platform in support of Simulation-Driven Product Development. As part of thatvision, we created DesignXplorer to leverage thepower of Workbench for parametric analyses.Workbench makes it easy to create and manageparameters. Setup is persistent, and updatesare automatic.

You can add DesignXplorers systems (goal-drivenoptimization, parameters correlation, responsesurface and six sigma analysis) to the Workbenchschematic with drag-and-drop simplicity. Theremote solve manager (RSM) allows for distributedsolve of design points.

DesignXplorer leverages these and other ANSYSstrengths to help you truly understand yourdesign and so that you can apply simulationto drive product development.

Design exploration can

provide useful insight

into designs, such as

understanding what

a selective catalytic

reductions system.

Automatically explore various design geometries to

obtain an optimal design with DesignXplorer.

Cameron used goal-driven optimization to determine the

clapper angle on a check valve. The engineering team

applied ANSYS DesignXplorer to discover and explore

a multitude of solutions; they generated trade-o plots

for 50 dierent sizes and pressure classes of the valve.

This line of points essentially a ow performance curve for a

wide range of feed conditions was generated for each of the

50 valves, thus providing solutions in hours rather than weeks.

Design Exploration for All Physics

ANSYS oers an unparalleled breadth ofengineering simulation solutions across a broadrange of disciplines that can accurately modelthe uid, structural, thermal and electromagneticphysics of any design. ANSYS workow technology including bidirectional CAD interfaces, meshingand post-processing tools simplies theprocess to help increase productivity and enableexploration. All of these tools are integrated in

the Workbench environment, so you can combinethem to meet your simulation needs.

DesignXplorer technology is available for allphysics within the ANSYS Workbench schematic.It supports analyses in which multiple physics areanalyzed independently or in a coupled manner.

Researchers at Advanced Engineering

Solutions leveraged DesignXplorer with

ANSYS Mechanical software to assess

design sensitivity on thermal perfor-

mance of a fuel cell stack.

Organizations in a wide range of industries use ANSYS design exploration tools to increase design understanding and product performance.

The team found that this approach shaved months o the development processand led to innovative designs through improved understanding of fuel cell behavior,

especially the impact of a wide range of design variables.

Design of Experiments and Response Surfaces

ANSYS DesignXplorer features a variety of DOEtypes, from basic Latin hypercube sampling (LHS)to central composite design (CCD) factoring tooptimal space lling (OSF) even to adaptivesparse grid or kriging methods. These scientic

methods subdivide your design space to ecientlydevelop a series of simulation experiments forexploring designs. The DOE table of design pointscan be solved in batch mode on your local machineor remotely distributed for a simultaneous solve.

Our powerful response surface technologiesinclude full second-order polynomial, kriging,non-parametric regression and neural networkapproaches. These serve to interpolate betweenthe data points in multidimensional space. Theycan be visualized as a 2-D or 3-D descriptionof the relationships between design variables

and design performance.

DesignXplorer can use the response surfaces as areduced-order model. For example, while lookingat optimization trade-os, the algorithm cansearch the response surface to rapidly solve manythousands of samples. You can also probe theresponse surface or add design points at will.

Optimization

Once you have explored the design and understandcorrelations and sensitivities, you may wantto optimize the design. DesignXplorer includesseveral algorithms that help identify the mostsuitable candidates taking into account multipleobjectives and performance trade-os.

When optimizing the air intake for an FSAE car, the University of Waterloo FormulaMotorsports team used DesignXplorer to quickly and eciently investigate designimpact on overall performance, eliminating the need for multiple prototype cycles.

The response surfacemethod visualizes therelationship betweeninput and outputparameters; theexample is an AnsoftDesigner model.

Trade-o charts help you to visualize possible andequivalent solutions to the optimization, providinginsight for determining the best trade-os to meetdesign goals.

Geometric Parameters

ANSYS Workbench supports CAD design parametervariations through our bidirectional CAD interfacesand ANSYS DesignModeler. In addition, youcan use ANSYS SpaceClaim Direct Modeler toparameterize neutral geometry formats.

Managing Simulation Data

Design exploration can generate large volumes ofdata. ANSYS Engineering Knowledge Manager(EKM) enables capture and management ofyour simulation data, along with workows andbest practices, in a searchable and sharableenvironment. The EKM tool can improve theeciency and productivity of simulation teams.

High-Performance Computing

Large parametric problems require superiorhigh-performance computing (HPC) to obtainhigh-delity results quickly. Advanced parallelprocessing eciently utilizes multiple multi-coreprocessors from a single machine or in a groupingof machines on a network. Thus, HPC enables you

to increase the number of design variations youcan compute in a given period, leading to better,more optimized products. Another signicantadvantage is getting your product to market in ashorter time frame. The end result is condencethat your design will thrive in the real world.

Our integrated toolkit means you can fully explore your design

as well as manage the wealth of data it generates.

Using design exploration to study a range of varia-tions, engineers at Power Systems Manufacturingdened blade parameters to be varied, assignedacceptable parameter ranges, and identiedvariables to optimize (blade natural frequenciesand peak steady stresses at several locations onthe compressor blade). Based on peak stress loca-tions, design space denitions were created. ANSYSDesignXplorer redened the CAD model and generatedthe series of design variations needed to carry outexperiments for the entire range of parameters.
