LMS Virtual.Lab Acoustics Revision 9

The LMS Virtual.Lab Acoustics Rev. 9 from LMS Engineering Innovation (lmsintl.com) includes features that are designed to address acoustic problems that may arise during digital product development. The Finite Element Method (FEM) for acoustics now incorporates Perfectly Matched Layer (PML) technology, which reduces the number of elements needed to solve noise radiation problems and enables the FEM feature to handle large industrial tasks, including noise radiation problems.

The Boundary Element Method (BEM) technology has been updated to a time-domain BEM, which is a time-based method for acoustic wave propagation applications. This allows users to see how acoustic waves spread throughout the acoustic field. This technology also combines LMS’ patented Acoustic Transfer Vector (ATV) with their Fast Multiple (FM) BEM solver introduced in LMS Virtual.Lab Rev. 8.

Last but not least, the new ray tracing technology is ideal for high-frequency acoustic work, such as wall absorption assessment.
