Creating Optimized External Aerodynamics with Virtual Wind Tunnels

Modern requirements around design and engineering require advanced methodologies to create as much efficiency as possible. This is especially true for the external aerodynamic considerations revolving around the automotive design process.  A vehicle’s fuel consumption, stability, engine cooling, interior cabin noise, windshield-wiper performance, and more are all influenced by aerodynamic forces, so it’s important to study the effects of these forces prior to production.

While performance can be tested in physical wind tunnels, doing so is extremely costly – and it can require numerous test runs to determine the changes needed to improve results. Virtual wind tunnel simulations provide an alternative by allowing design engineers to study aerodynamic loads prior to physical testing – reducing the need for physical wind tunnel experiments during a vehicle’s development process. In this whitepaper, you’ll learn how Altair’s HyperWorks Virtual Wind Tunnel (HyperWorks VWT) brings new levels of accuracy and speed to predicting a vehicle’s external aerodynamic performance.

When working around aerodynamic design considerations, it’s important to work with solutions which have key efficiency features. These capabilities include:

  • Accurate, robust and scalable solver
  • Advanced meshing
  • Advanced physics capabilities
  • Friendly, intuitive user environment
  • Advanced CFD post-processing
  • Optimized workload management

Remember, external aerodynamic simulation plays an important role in modern automotive design. A vehicle’s fuel consumption, stability, engine cooling, interior cabin noise, windshield-wiper performance, and more are all influenced by aerodynamic forces, so it’s important to study the effects of these forces prior to production.
