This simple tutorial model shows how to set up a parametric sweep over a number of frequency bands (octaves or 1/3 octaves) and remesh once per band. A frequency sweep is performed within each band, which now has an adequate mesh resolution. This approach saves some computational effort ... En savoir plus
FSI analysis of a sports car side door and side rear view mirror. The model is based on large eddy simulation analysis of a sports car. The flow field is used for a structural analysis of the side mirror and side door to estimate the flow-induced vibrations. En savoir plus
This example shows how to set up a piezoelectric transducer problem following the work of Y. Kagawa and T. Yamabuchi. The composite piezoelectric ultrasonic transducer has a cylindrical geometry that consists of a piezoceramic layer, two aluminum layers, and two adhesive layers. The ... En savoir plus
This example resembles the well-known double-slit interference experiment often demonstrated in schools with water waves or sound. The model mimics the plane-wave excitation with two thin waveguides leading to slits in a screen and computes the diffraction pattern on the opposite side of ... En savoir plus
This tutorial computes the transfer matrix of a tube and coupler measurement test setup. This type of setup is used for standardized testing, for example, for miniature loudspeakers or hearing aids. The Port boundary condition in Pressure Acoustics, Frequency Domain is used together ... En savoir plus
This model presents two examples of topology optimization of the magnetic circuit of a loudspeaker driver. A first optimization is used to find the design of a nonlinear iron pole piece and top plate that maximize the BL factor at the resting position (small displacements), while ... En savoir plus
This small tutorial model shows how to set up a model with a solid mechanics and a pressure acoustics domain including a common perfectly matched layer (PML). The PML is used to model an open or infinite domain for both the elastic waves and the pressure waves. Three configurations of ... En savoir plus
Diesel particulate filters (DPFs) are designed to remove and filter soot (diesel particles) from the exhaust of diesel engine vehicles. The filters in such systems are typically structured with long, air-filled channels surrounded by a porous medium that retains the soot. Although the ... En savoir plus
Prevent shaking windows and enhance the sound experience by careful positioning of the loudspeakers in your room. This tutorial analyzes the low frequency response of a living room to the woofer units of two loudspeakers, and solves for the eigenfrequencies of the room. The room geometry ... En savoir plus
This example shows how to compute thermally induced stresses in a turbine stator blade using the Thermal Stress, Solid interface. The conditions within gas turbines are extreme. The pressure can be as high as 40 bar, and the temperature more than 1000 K. Any new component must therefore ... En savoir plus
