Core Simulation Techniques and Acoustic Modeling

Finite Element Method (FEM) and Fluid-Structure Interaction

The software employs the Finite Element Method (FEM) to accurately simulate acoustic behavior within enclosed spaces, such as vehicle cabins or electronic device interiors. This FEM approach is particularly effective for calculating acoustic cavity modes and understanding how vibrations from structural components excite sound within these confined volumes. Furthermore, PowerACOUSTICS supports fluid-structure interaction (FSI) analyses, crucial for modeling how acoustic pressure waves interact with vibrating structures, thereby predicting noise transmitted into passenger compartments.

Boundary Element Method (BEM) for Exterior Sound Radiation

For exterior noise problems, DS SIMULIA PowerACOUSTICS 2026 utilizes the Boundary Element Method (BEM). This technique is highly efficient for modeling sound radiation into open environments without the need to discretize large air volumes. BEM is instrumental in simulating noise originating from external sources, such as engine compartments or aerodynamic sources, and predicting its propagation patterns. This dual approach—FEM for interior and BEM for exterior acoustics—provides a comprehensive solution for complex acoustic challenges.

Specialized Acoustic Analyses

PowerACOUSTICS offers a suite of specialized analyses tailored for vibro-acoustic engineering. These include detailed frequency response analyses to understand acoustic behavior across a range of frequencies, evaluation of random vibration response to predict acoustic durability under unpredictable loads, and transmission loss assessments to quantify how effectively materials or structures block sound transmission. These capabilities allow engineers to thoroughly investigate acoustic performance under various conditions.

Advanced Acoustic Metrics and Post-Processing Tools

Beyond raw acoustic data, DS SIMULIA PowerACOUSTICS 2026 provides sophisticated post-processing tools for in-depth analysis and visualization. Engineers can visualize acoustic pressure fields to identify areas of high sound intensity and analyze sound power radiation contours to understand noise source directivity. A key differentiator is the software’s support for psychoacoustic metrics, including loudness, sharpness, and tonality, which help correlate simulation results with human auditory perception and guide efforts to improve sound quality and user experience.
