LMS Virtual.Lab Acoustics
Solve Mega-Problems…Even Faster
LMS Virtual.Lab FEM (Finite Element Method) Acoustics
LMS Virtual.Lab FEM Acoustics offers an advanced method for simulating acoustics using FE meshes while still modeling the propagation area. Since these models tend to be quite large, advanced computing techniques and solvers are an absolute must. With LMS Virtual.Lab Rev 9, FEM acoustics reaches an even-higher level with more solver options and high-tech routing features to solve practically any application no matter what size, frequency range or robustness.
- FEM iterative solvers for significant performance increases with huge industrial models
- PML (Perfectly Matched Layer) substantially reduces the number of required elements to solve mega problems much more efficiently. It is a superbly efficient method for large sound radiation problems Watch movie here
- Automatic Domain Decomposition lets users split very large FEM models into domains automatically while using efficient parallel computing processes. Ideal for higher frequencies.
- Stabilized FEM: This alternative approach results in far better accuracy for similar-size models. User can confidently use reduced-size models without risking result validity.
LMS Virtual.Lab BEM (Boundary Element Method) Acoustics
Enter the Time Domain
As the absolute market leader in BEM acoustics, LMS continues to innovate with LMS Virtual.Lab Rev 9. 
- Time domain BEM: A new time-based method for acoustic wave propagation applications. Users can see how the acoustic waves spread throughout the acoustic field. Watch movie here
- FMBEM ATV combines LMS’ patented ATV (Acoustic Transfer Vector) technology with the truly unique FMBEM (Fast Multipole BEM) solver introduced in LMS Virtual.Lab Rev 8. It is the ultimate way to efficiently solve mega-problems like high-frequency acoustic structural radiation issues. Watch movie here
- FMBEM (fully coupled): a technique supporting strong coupling between structural and acoustic domains.
LMS Virtual.Lab Ray Tracing
Brand-new LMS technology: new solver for high-frequency acoustic work
This brand-new ray tracing solver is ideal for interior acoustics applications, such as wall absorption assessment. It is extremely efficient for high frequency acoustics. Watch movie here
LMS Virtual.Lab Source Identification
Inverse Numerical Acoustics: this inverse technique accurately determines vibration sources for a better understanding of noise problems and ultimately a better noise and vibration system optimization. By coupling a near-field measurement with Inverse Numerical Acoustics, users can simulate vibration sources to use as loads for accurate forward acoustic predictions (near field measurement applied for far field simulation).
