This model demonstrates how to setup a Time Domain to Frequency FFT study for a distributed Bragg reflector (DBR) structure. The results agree well with the results of a regular Frequency domain study. 詳細を見る
The Bessel panel is a way to arrange a number of loudspeakers so that the angular sound distribution resembles that of a single speaker. This model combines five Bessel panels in the same pattern to approximate a purely radial sound field. The speakers are driven with different ... 詳細を見る
The model simulates atmospheric corrosion of a galvanic couple, comprising of an Al-Co-Ce metallic coating and an aluminum alloy, which is in contact with electrolyte film of 100 micrometer thickness. The corrosion inhibitors are released from the metallic coating and are transported ... 詳細を見る
This tutorial presents a study of positive and negative corona discharges in dry air at atmospheric pressure. The discharges are sustained within two electrodes in a coaxial configuration by a high voltage DC source applied to the inner electrode. Two different types of models are used: ... 詳細を見る
In complex mechanical systems, it can be challenging to find an optimal (or even good enough) solution only through engineering insight or trial-and-error procedures. Using mathematical optimization methods can then be an efficient path to a better design. In this example, a link ... 詳細を見る
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 ... 詳細を見る
A tapered optical waveguide structure is used for matching two waveguides having different geometric cross sections and/or different material parameters. The tapered waveguide has one geometric cross section at the input plane and another cross section at the output plane. In between ... 詳細を見る
Helmholtz resonators are used in exhaust systems, as they can attenuate a specific narrow frequency band. The presence of a flow in the system alters the acoustic properties of the resonator and the transmission loss of the subsystem. In this tutorial model, a Helmholtz resonator is ... 詳細を見る
This model demonstrates how to use the Control Function feature to perform shape optimization on a rectangular horn for an improved on axis response. The results of the initial design are exported to a new component via a Filter dataset. Further, the off-axis spatial response is improved ... 詳細を見る
Many piezoelectric materials are ferroelectric. Ferroelectric materials exhibit nonlinear polarization behavior, such as hysteresis and saturation at large applied electric fields. In addition, the polarization and mechanical deformations in such materials can be strongly coupled due to ... 詳細を見る
