Why a Virtual Wind Tunnel?

External aerodynamics analysis plays a key role in modern automotive design. But while performance can be tested in physical wind tunnels, doing so is extremely costly — and often numerous test runs are required to determine the changes needed to improve results.  Virtual wind tunnel simulations provide an alternative by allowing design engineers to study aerodynamic loads – reducing the need for physical wind tunnel testing.

Live Webinar: Cray and Altair Solutions

In this webinar, Altair and Cray will describe an advanced and high-performance virtual wind tunnel solution complete with recommended configurations based on system size. The speakers will present the latest performance and scalability testing results from Altair’s HyperWorks Virtual Wind Tunnel software running on Cray XC30 systems, using both small and large (1 billion element) models. The speakers will discuss details of the performance testing and recommended hardware configurations, including both smaller hundred-core clusters and larger thousand-core supercomputers.

Virtual Wind Tunnel imageExperts will be also available to answer audience questions and advise on how to optimize your own environment to achieve faster turnaround times for external aerodynamic simulations.
