HyperWorks Virtual Wind Tunnel

Altair

Altair has introduced HyperWorks Virtual Wind Tunnel, a streamlined and vertical application designed to improve wind tunnel simulation for the automotive industry. Central to the solution is AcuSolve, Altair’s CFD solver that enables HyperWorks Virtual Wind Tunnel to predict the flow field and flow separation using steady-state and transient simulation for faster and more accurate results. The fluid-structure interaction solution from AcuSolve allows more realistic and comprehensive automotive virtual wind tunnel simulation by considering the flexibility of structures.

Another advantage of HyperWorks Virtual Wind Tunnel is its advanced meshing capabilities. Built on a powerful meshing technology, HyperWorks Virtual Wind Tunnel comes with a fast, fully-automated unstructured mesher with boundary layers. Volume meshing for an external automotive aerodynamics analysis — including the underbody, underhood compartment and boundary layers — can be completed in less than two hours. The CFD solver at the core of HyperWorks Virtual Wind Tunnel is highly tolerant of element qualities, with the ability to manage badly distorted elements unavoidable for complex geometries. The solver’s flexibility eliminates the time-intensive mesh optimisation step often required with other solutions, dramatically reducing meshing time.

HyperWorks Virtual Wind Tunnel provides a friendly, intuitive user environment and a highly automated setup process. The simulation can be submitted easily to high-performance computing systems from within the HyperWorks Virtual Wind Tunnel environment.
