This example uses the thermal expansion of a laminated composite shell model to demonstrate the use of the feature Thermal Contact, Interface, applied on interfaces between layers in a laminated composite shell. The first study is computed neglecting this additional thermal resistance in ... Mehr lesen
A time-varying current induces a time-varying magnetic field. The magnetic field induces currents in neighboring conductors. The induced currents are called eddy currents. In this model, the phenomenon is illustrated by a time-harmonic field simulation as well as a transient analysis, ... Mehr lesen
Dieses Tutorial demonstriert eine vollständige elektro-vibroakustische Analyse eines konzeptionellen elektrostatischen Lautsprechertreibers, der aus einer dünnen leitenden Kunststoffmembran besteht, die sich zwischen zwei perforierten Metallblechen, den Gittern oder Statoren, befindet. ...

Micromirrors are used in certain MEMS devices to control optic elements. This example model illustrates a mirror that is initially actuated for a short time and then exhibits damped vibrations. It simulates a vibrating micromirror surrounded by air and uses the Thermoviscous Acoustics, ... Mehr lesen
This model demonstrates two approaches to model the acoustics in a generic nacelle with an acoustic liner and a background flow. The first method uses the Compressible Potential Flow and the Linearized Potential Flow, Frequency Domain interfaces, while the second, more detailed approach, ... Mehr lesen
In applications where pressure waves and elastic waves propagate in porous materials filled with air both thermal and viscous losses are important. This is typically the case in insulation materials for room acoustics or lining materials in car cabins. Another example is porous materials ... Mehr lesen
This model demonstrates the simulation of surface dielectric barrier discharges (DBDs) using the Electric Discharge interface. The formulation incorporates a comprehensive set of physical processes, including charge transport, impact ionization, electron attachment, recombination, and ... Mehr lesen
This example of a plasmonic waveguide filter shows that the waveguide rejects the electromagnetic radiation of the wavelength between 1.4 um and 1.6 um, but allows the rest of the wavelength. The silver material can be modeled using the Drude-Lorentz approximation, with ε∞ = 3.7, ωp = 13 ... Mehr lesen
This model represents a stove in a living room. A radiation study is performed with the Surface-to-Surface Radiation physics interface. It shows the intensity of the stove radiation received on different surfaces of the room. Mehr lesen
These models introduce how to perform convolution via the convolution integral, discrete convolution, and convolution theorem. Specifically, they show how to implement convolution by applying these methods to the low-pass filtering of a room impulse response (IR) and the auralization of ... Mehr lesen
