There are as many model requirements
Vibro-acoustic engineers need the right model at the right time, and there are as many model requirements as there are milestones in a project - sometimes engineers require fast overnight computation, sometimes what they desire is extreme precision. The new VA One provides this flexibility along with a new automatic model checking function, which ensures that computations will not fail overnight because of some missing parameter.
The new DMP (Distributed Memory Processing) BEM solver now delivers superior performance on High Performance Computing architectures, reducing computational times by a factor of 10 for large cases. It enables faster calculations, which is especially beneficial when faced with tough challenges such as the assessment of vehicle pass-by noise that will be required of automotive OEMs by upcoming regulation UN/ECE R51.03.
The new VA One also provides automated user assistance when setting up a large number of load cases (e.g. for powertrain run-up simulations), reducing import time from several hours to only a few seconds. The objective is to minimize time-consuming jobs by automating them, so engineers can focus on high value-added tasks.
Automatic coupling with the open source CFD software OpenFOAM® is added in this latest version of the software, enabling vibro-acoustic engineers to make quick predictions of the performance of their designs in the presence of stationary flow components. The new utility generates standard OpenFOAM® meshing automatically and updates the vibro-acoustic models with local fluid dynamics properties (e.g. Mach vectors) for easy integration into VA projects involving propagation in ducts, mufflers, and other similar cases. The full automation of CFD model set-up, meshing and post-processing from within VA One makes CFD calculations easily accessible to non CFD-specialists.
