Altair’s general purpose CFD solver AcuSolve is applying a finite-element technology to solve the fluid dynamic equations on an unstructured mesh topology. The finite-element approach yields high accuracy with very low requirements on mesh quality. The flow solver is developed for parallel execution on shared and distributed memory computer systems yielding quick turnaround times for typically large external aerodynamic model.
In this presentation, external aerodynamic results for classical automotive benchmarks as well as realistic vehicles are discussed. The fluid-structure-interaction (FSI) capabilities of AcuSolve are used to study the deflection of an automotive rear wing.
Furthermore , an external aerodynamic study of a wind turbine is presented including FSI effects of the rotor blades.
