Case Study: Toyota Motor Europe achieves 10x faster HVAC noise simulation with Cadence Design Systems

Toyota Motor Europe cuts HVAC noise simulation time by 90% with Cadence

The customer, Toyota Motor Europe, faced the challenge of HVAC noise becoming a major comfort concern in quieter electric vehicles. They partnered with vendor Cadence Design Systems to utilize their GPU-accelerated computational fluid dynamics (CFD) solution for faster and more accurate simulation.

Cadence's solution enabled Toyota to perform full airflow and noise simulation in under six hours, which was ten times faster than traditional CFD methods. The results were highly accurate, with simulations within ±3dBA of physical tests. This 90% reduction in simulation time allowed for real-time design decisions, significantly reducing physical testing and speeding up development cycles.
