Perform Analysis for Mid to High Frequency and Acoustic Simulations for Complex Structural Acoustic Systems

EFEA allows rapid evaluation of the vibration levels and the interior noise in complex systems. Design changes and the use of treatment configurations can be assessed for achieving the desired performance without an excessive increase in the weight of the system.

The hybrid finite element analysis (HFEA) extends the applicability of finite element models to higher frequencies for vibration and noise simulations. The method has been validated in the past in several automotive applications.
