This presentation focuses on high-performance parametric computing for computational fluid dynamics (CFD) 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

High Performance Computing (HPC) at ANSYS:
An ongoing effort designed to remove
computing limitations from engineers who
use computer aided engineering in all phases
of design, analysis, and testing.
It is a hardware and software initiative!

Summary
Design Impact
HPC Parametric
ANSYS provides a systematic approach to helping
engineers to evaluate multiple product design ideas
across a range of conditions and design parameters
within a single environment, leading to enhanced
product performance and integrity.

Application Example
Objective
Optimize race car performance by predicting
aerodynamics of the air intake system.
ANSYS Solution
• The Coburg Automobile Team (CAT) generated a
parameterized CAD model, and improved the car’s air
intake system using ANSYS CFD within the parametric
ANSYS Workbench environment
• With an automatic optimization loop in ANSYS
Workbench, CAT Racing optimized the number of
guide vanes, their opening angle of the air box and
other parameters.
Design Impact
The new air intake system generated the correct amount
of torque at the right speed which enabled CAT Racing
to win two second-place finishes.

Application Example
Objective
Speedup the optimization process of a wing design.
Conventional methods typically take a couple of months.
ANSYS Solution
• Piaggio Aero Industries teamed with the University of
Rome Tor Vergata to validate a new optimization
method that generates a single mesh and morphs it
to any new geometry.
• ANSYS DesignXplorer was used to parametrically
drive RBF Morph to map out the complete design
space, identify optimal design, and validate its
robustness in just a few weeks.
Design Impact
With ANSYS software, the design optimization took a
couple of weeks, less than a tenth of the time required
to optimize the design using conventional methods.
