EFEA

What is EFEA?

EFEA is a solver that performs analyses for acoustic and medium to high frequency simulations for complex structural-acoustic systems.

Finite Energy Finite Element Analysis (EFEA) can perform medium to high frequency acoustic and vibration simulations for complex structural - acoustic systems. EFEA code is computationally efficient and easy to use. It is compatible with cad databases used during product development and can be easily integrated into a multidisciplinary design environment. This unique technology offers a competitive advantage to MES customers and optimizes structural simulations - acoustic with other analyses during the design process.

Key features and benefits

The EFEA method uses energy-based primary variables instead of looking for an offset-based solution, such as the Finite Element Analysis (FEA) method. This results in significant computational efficiency and the use of only a small fraction of elements compared to FEA.

The EFEA method is similar to The Statistical Energy Analysis (AAE), because it uses variables of vibratory and acoustic energy. However, the EFEA model maintains a direct connection to physical design through its finite element-based model. No modal density information is required in EFEA, this increases accuracy. Structural damping and acoustic treatment can be specified in the physical part of the model in which it is actually applied.

Finite element-based visualization of the results offered by EFEA fits well into a design process for developing efficient noise reduction strategies.
