Our advanced acoustic simulation technology has been integrated into Bramble CFD’s platform, offering automotive manufacturers a faster, more cost-effective solution for cabin noise reduction and aero-acoustics testing.

Reducing the more noticeable interior noise in electric vehicles will become a differentiator in the automotive market. Therefore this new capability comes at the right time, allowing automotive engineers to simulate and optimise acoustic performance cost-effectively.
The integration delivers full car aero-acoustics simulation at a lower cost and faster turnaround time.

Mark Allan, Product Lead Acoustics, Zenotech commented:

“Zenotech is proud to support Bramble CFD and their users with our next-generation aero-acoustic and zCFD tools. We’re excited to see the benefits of this integration to the automotive industry, including luxury brands, such as Aston Martin, as well as how the tool will be applied in new ways.”

Ivor Annetts, Managing Director of Bramble CFD said:

“This integration transforms how automotive engineers can approach acoustic design. By reducing simulation time from weeks to hours and significantly lowering costs, we’re making professional-grade acoustic testing accessible to more manufacturers and engineering teams.”

Our aero-acoustics tool optimises acoustic noise prediction, boosting efficiency and offering transformative turnaround times:

• Semi-automatic acoustic mesh generation with optimal time step, providing high-quality refined cartesian meshes.
• Saves time as no additional CAD clean-up is required for acoustic mesh generation; the RANS surface mesh provides the geometry.
• Provides aerodynamic broadband noise predictions based on steady-state RANS simulations.
• Diffraction and refraction effects can be included in the model.

Bramble is a cloud platform for CFD simulations, providing support for the pre- and post-simulation process, increasing productivity and creating consistency between simulations.

Key features of the integration with Zenotech’s tools:

• Run full car acoustic simulations in just 4 hours.
• Run aero-acoustics on automotive, buildings, aerospace and HVAC
• Test both internal and external acoustics
• No licence or subscription fees

By using the new integrated aero-acoustics tool, Aston Martin dramatically improved their acoustic engineering process, boosting efficiency and innovation. Benefits include speeding up the aero-acoustic simulation process (from 3 weeks to just 24hrs!) and providing a single environment for simulation and analysis rather than switching between packages.

The solution accelerated development, reduced costs, and freed engineers to focus on innovation. Streamlined workflows and precise acoustic data enabled rapid design iterations, guaranteeing the high quality synonymous with the luxury automotive brand.
