LMS Virtual.Lab Acoustics Rev 9 takes acoustic simulation to the next level

A core development focus has been to expand the FEM acoustic solver so that it can handle huge industrial tasks, including large noise radiation problems. This is possible thanks to PML (Perfectly Matched Layer), a technique that substantially reduces the number of required elements to solve noise radiation mega-problems more efficiently.

Other critical work has occurred in the area of LMS’ BEM technology with the addition of a time-domain BEM solver, allowing acoustic engineers to do realistic simulations and gain more insight into time-related acoustic issues. In addition, the new inverse numerical acoustics solution helps determine realistic vibration sources for a better noise and vibration system optimization.

LMS continues to lead the innovation race in the area of Fast Multiple BEM (FMBEM) with the addition of patented ATV (Acoustic Transfer Vector) technology to the FMBEM solver.

With LMS’ brand-new ray tracing technology integrated in LMS Virtual.Lab Rev 9, acoustic engineers will be able to handle the full audible frequency range, including sound system optimization in aircraft, train or vehicle interiors.

Enhanced for aero-acoustic engineers, LMS Virtual.Lab Aero-Acoustics Rev 9 adds a variety of new features, such as conservative mapping for more accurate predictions, CFD-based quadruples noise sources, and improved fan formulation to provide ultimately more ways to address flow-induced noise.

“As the market leader in acoustic simulation, LMS is committed to providing the fastest, most robust and most efficient solutions. That’s why our on-going focus on R&D ensures that year after year our customers continue to have the best-possible tools available to meet the ever-changing challenges of the acoustic simulation community,” commented Stefaan Goossens, Vice-President Simulation at LMS International.
