A wideband antenna study, such as an S-parameter or far-field pattern analysis, can be obtained by performing a transient response analysis and a time-to-frequency fast Fourier transform (FFT). This model runs a time dependent study first and then transforms the dependent variable, the ... En savoir plus
This model shows how to simulate carburization and quenching of a steel gear. Diffusion of carbon into the surface of the gear affects the onset of martensitic transformation. Residual stresses are computed, and it is shown that high residual compressive stresses appear at the root of ... En savoir plus
In this tutorial the acoustic behavior of a duct or waveguide with a right angled bend is analyzed. The model uses port boundary conditions at the inlet and outlet. The ports can capture and treat non-plane propagating modes in waveguides, extending the analysis above the first cutoff ... En savoir plus
Electrochemical codeposition is a common low-cost method for producing metal alloys. This tutorial model demonstrates electrodeposition of a nickel (Ni)–phosphorous (P) alloy. The model accounts for charge and mass transport of a multitude of species along with multiple electrode ... En savoir plus
This model simulates electrical breakdown in an atmospheric pressure gas. Modeling dielectric barrier discharges in more than one dimension is possible, but the results can be difficult to interpret because of the amount of competing physics in the problem. In this simple model the ... En savoir plus
Chemical vapor deposition (CVD) allows a thin film to be grown on a substrate through molecules and molecular fragments adsorbing and reacting on a surface. This example illustrates the modeling of such a CVD reactor where triethyl-gallium first decomposes, and the reaction products ... En savoir plus
Transmission lines are used when the frequency of the electromagnetic signals is so high that the wave nature of the signals must be taken into account. A consequence of the wave nature is that the signals are reflected if there are abrupt changes of the characteristic impedance along ... En savoir plus
The double barrier structure is of interest because of its application in semiconductor devices such as resonant-tunneling diodes. This verification example demonstrates the Schrödinger Equation interface to set up a simple 1D GaAs/AlGaAs double barrier structure to analyze the ... En savoir plus
In this model, two concave mirrors are placed at a distance and a ray is released from a point inside the cavity. Then the ray is traced for a predefined time period that is sufficiently long. Ray tracing continues until the predefined computation time has passed if the laser cavity is ... En savoir plus
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 ... En savoir plus
