Boundary Element Acoustics

Lab Boundary Element Acoustics is an entry-level, easy-to-use acoustic simulation tool to predict and improve the sound and noise performance of a broad range of systems. With straightforward models and embedded solver technology, engineers can acquire results faster without compromising accuracy. LMS Virtual.Lab Boundary Element Acoustics uses the boundary element method ( BEM) , which effectively reduces complex 3D geometry to 2D surface dimensions. Only the surface areas of the structural systems that are vibrating or scattering sound need to be modeled. BEM model sizes are typically limited to a few thousand elements, resulting in relatively small, easy-to-create, check and handle models compared to complex 3D finite element models. These reduced models deliver results in a shorter timeframe, helping users to quickly evaluate the acoustic design performance. LMS Virtual.Lab Boundary Element Acoustics can accurately model structuralacoustical coupling phenomena, common in lightweight structures when acoustic sources make the structure vibrate. For example, strong variations in engine pressure will make the engine intake vibrate, generating additional radiated noise. This solution tackles both internal and external radiation problems and covers a broad range of applications, such as transmission loss through panels, electronic or household equipment sound quality and radiated noise. The solution runs transparently with other CAE codes and includes seamless links to Abaqus, Ansys, CATIA CAE, I-DEAS, Nastran, and Permas. It is an ideal starting point for advanced and specialized applications.
