Why Efficient middle to high-frequency vibro-acoustic simulation?

EFEA offers efficient middle to high-frequency vibro-acoustic simulation using EFEA. It integrates easily with CAD and multi-disciplinary design, supporting engineers in analyzing complex structural-acoustic systems. The tool streamlines simulations, saves time, and provides manufacturers a competitive advantage in product development.

Benefits

Finite Element Model:
A finite element model is used for mid to high frequency analysis. It complements conventional finite element solvers and is a common model development process.
Computational Efficiency:
Alternative designs can be evaluated rapidly. Fast turn around times allow simulations to influence the design.
Versatility:
EFEA is applicable to noise and vibration simulations in different engineering disciplines with a wide knowledge base.

Featured Capabilities

Accuracy

Many validation studies are available in the literature to provide reliable results.

Data Export

The data file for the EFEA solver uses the NASTRAN format. The model can be generated in Simcenter HyperMesh® and exported in NASTRAN format.

Post-Processed Visualization

The results from the EFEA solver are reported in NASTRAN format. The results can be post-processed and visualized in HyperMesh.
