This model combines pressure acoustics and ray acoustics to perform a full frequency range analysis of the room impulse response of a small smart speaker. The source characterization in the ray tracing model is based on a full multiphysics model of the transducer and compares two source ... Mehr lesen
The Highly Accelerated Stress Test (HAST) is a testing technique to precipitate failure of electronic devices under elevated temperature and high humidity environment. This model demonstrates the structural analysis of a plastic encapsulated IGBT module under the HAST testing condition. ... Mehr lesen
This is a benchmark model for rigid body dynamics. This model simulates the dynamic behavior of "Andrew’s squeezing mechanism", which is force driven and requires a very small time scale. Various angles in the mechanism are compared with the results from the reference. Mehr lesen
This tutorial model shows how to model a microspeaker located in a smart phone including the radiation through and interaction with the acoustic port that connects to the exterior. The model demonstrates a linear frequency domain analysis as well as a nonlinear time domain analysis. A ... Mehr lesen
This app demonstrates: Light theme This app allows you to evaluate cross-section data for a wide range of American and European standard beams. Given a set of forces and moments acting on the section, you can also compute a detailed stress distribution. Calculated cross-section data ... Mehr lesen
This tutorial simulates a standard test and benchmark model for perfectly matched layers (PMLs) as absorbing boundary conditions in the time domain. It involves the propagation of a transient Gaussian pulse with no flow. The Pressure Acoustics, Transient interface is used together with ... Mehr lesen
The elastoacoustic effect is a change in the speed of elastic waves that propagate in a structure undergoing static elastic deformations. The effect is used in many ultrasonic techniques for nondestructive testing of prestressed states within structures. This example studies the ... Mehr lesen
This is a benchmark model for the linearized Euler interface of the Acoustics Module. The model is from the NASA "Fourth Computational Aeroacoustics (CAA) Workshop on Benchmark Problems (2004)". The model results are compared to an analytical solution by Agarwal et al. (AIAA Vol. 42, No. ... Mehr lesen
