These models are featured in the blog post Analyze Violin Tone and Volume with Multiphysics Modeling. One applies acoustic-structure interaction to study how the air mode resonance is affected by the coupled vibrations in the violin body. The other uses a potential flow approximation to ...

This verification model analyzes the acoustics of two coupled rooms using the Acoustic Diffusion Equation interface of the Acoustics Module. The results of the model agree with numerical results that are validated against measurements in a reference paper. Mehr lesen
This model uses the Ray Acoustics interface to extract statistical information about a room. Two examples of rooms are analyzed: The staircase from the One-Family House Acoustics tutorial model A long corridor The models compute the mean free path as well as the reflection frequency ... Mehr lesen
Finding acoustic eigenmodes in problems solved with linearized convected acoustic interfaces can be a challenging task. The solution will most often return several non-acoustic vorticity and entropy modes. These are highly damped waves that do not propagate at the speed of sound but with ... Mehr lesen
It can in many cases be difficult to get accurate material properties for porous materials. Measuring the properties to high precision can involve lengthy measurements using different techniques. It can therefore be interesting to understand how uncertainties in different material ... Mehr lesen
The sound distribution from a TV in a two-room apartment is computed. The simulation demonstrates the use of the Acoustic Diffusion Equation interface to get a quick and simple estimate of the local sound pressure level. For increased accuracy, an analytical expression for the direct ... Mehr lesen
Die Lösung sehr großer Druckakustikmodelle im Frequenzbereich kann eine Herausforderung darstellen. Für die Standard-Physikkonfigurationen und die standardmäßige quadratische Lagrange-Diskretisierung gibt es mehrere Vorschläge für iterative Löser. Bei sehr großen Modellen kann es ... Mehr lesen
This model analyzes the uncertainty in focused ultrasound induced tissue heating. The material properties for the tissue mimicking material, including the uncertainty, are taken from the FDA Medical Device Development Tool: Tissue Mimicking Material (TMM) for Preclinical Acoustic ... Mehr lesen
