Published on

This presentation focuses on high-performance parallel 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

  10. 10. © 2014 ANSYS, Inc. July 11, 201410 Application Example Benefit of HPC Parallel - Examine More Design Variants Objective Develop a steerable conductor for enhanced oil recovery. ANSYS Solution • Stress analysis of hydraulic deflection housing using ANSYS Mechanical. • Use ANSYS HPC technology to solve a typical model with about 750K elements and many contacts in an hour or less, compared to about six hours without parallel processing. Design Impact Parallel processing makes it possible to evaluate five to 10 design iterations per day, enabling Cognity engineers to rapidly improve their design. Images courtesy of Cognity Ltd.

  11. 11. © 2014 ANSYS, Inc. July 11, 201411 Application Example Benefit of HPC Parallel - Simulate Larger or More Complex Models Objective Develop components for aircraft, rocket and gas turbine engines. ANSYS Solution • ANSYS structural mechanics simulations calculate temperature and stress time history of models up to 500,000 nodes. • Key to the selection of ANSYS structural mechanics was the program’s scalability – both in terms of parallel performance and the business model to support the order of magnitude increase in the number of design-point analyses to be performed. Design Impact Because of the increase in model size and number of calculations required, Volvo Aero leverages HPC to help track engine part wear, saving customers service and replacement costs.
