This presentation focuses on high-performance parametric computing for structural mechanics simulations! It is part of a series of 4 presentations in which - by means of real-world customer examples - we want to share with you some benefits of HPC and performance data as well as some background articles. For convenience, we’ve split them up by major solution areas: 1: High-Performance Parallel Computing for FEA 2: High-Performance Parallel Computing for CFD 3: High-Performance Parametric Computing for FEA 4: High-Performance Parametric Computing for CFD

Application Example
Benefit of HPC Parametric
- Enhance Product Performance Faster
Objective
Develop quieter diesel engines faster.
ANSYS Solution
• Use ANSYS Workbench to set up the coupled
simulation workflow for acoustic simulations.
• Generate each model automatically using the
parametric capabilities of ANSYS Workbench.
• Use ANSYS HPC and ANSYS HPC Parametric Pack
licensing to solve these computationally intensive
acoustic simulations.
Design Impact
A cost-effective HPC parametric licensing solution was
employed to simulate large-scale parametric
frequency variations of engine components. Solution
time for the acoustic simulations was reduced by 93
percent using ANSYS HPC technology.

Application Example
Objective
Ensure that high quality standards are met and reduce
the number of prototype testing iterations.
ANSYS Solution
ANSYS DesignXplorer enabling Xerox engineers to
perform numerous design of experiments (DOEs) to
study the sensitivity of changes in key product variables
such as part manufacturing tolerances, operating
temperatures of the machines or differences in print
media.
Design Impact
ANSYS has enabled Xerox engineers to quickly simulate
many printer components, and to earlier filter out
marginal designs in the design process. Over-designed
components can be cost reduced and amount of
product testing can be reduced as well.

Application Example
Objective
Develop and deliver quieter brakes by evaluating
numerous brake designs prior to building expensive
and long lead-time prototypes.
ANSYS Solution
A parametric, persistent simulation data flow
combines CAD, nonlinear contact, prestress-effects,
and a complex modal analysis for fast and accurate
brake squeal solutions.
Design Impact
The ability to automatically simulate many design
points to quickly iterate to a brake design that meets
noise requirements while delivering the best
combination of performance, cost, weight, size and
other factors.

Application Example
Objective
Develop best performing graphite electrodes faster.
Real world testing extremely cost intensive, because of
high temperature range of more than 3000° and long
process time.
ANSYS Solution
• Parameter identification by virtual DOE helps to
reduce the number of real-world tests.
• Simultaneous computation reduces the overall time
to get the needed answers from multiple weeks to
less than one week.
Design Impact
The new parametric licensing provides the SGL Group a
competitive advantage because they can meet
customer requirements faster and more cost effectively.
