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

  9. 9. © 2014 ANSYS, Inc. July 11, 20149 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. Enhance product performance faster Ensure product integrity Increase development speed
  10. 10. © 2014 ANSYS, Inc. July 11, 201410 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.

  11. 11. © 2014 ANSYS, Inc. July 11, 201411 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.
