This model shows how to compute the thickness of a thermally evaporated gold film. The thickness of the deposited film is computed both on the walls of the chamber and on the sample. En savoir plus
The eigenfrequencies of a rotating blade are studied in this benchmark. It shows how stress stiffening and the combined effect from stress stiffening and spin softening affects the fundamental eigenfrequency. High rotational speed in rotating machineries can result in centrifugal forces ... En savoir plus
This model shows a setup of two parallel wires with a constant current running through both. Their cross-sections are successively reduced until a set force per unit length is reached. En savoir plus
This tutorial introduces a workflow typical of creating geometry for simulation by using Sketch mode to draw complex shapes. Follow the step-by-step instructions to draw the geometry for the analysis of a light bulb. The physics setup is described in the model Free Convection in a Light ... En savoir plus
Biconical antennas are popular for very high frequency (VHF) measurement because they support a wide frequency range. They are also useful for electromagnetic compatibility (EMC) testing where the antenna can be used as an RF source in susceptibility or immunity test. This model ... En savoir plus
This example benchmarks a NAFEMS validation model of a friction contact problem with an elastoplastic material model. A thin metal sheet is forced into a die by a punch. Both the compressing displacement and the release of the punch are modeled in order to compute the forming angle (at ... En savoir plus
This simple model demonstrates how to use the Semiconductor Optoelectronics interfaces to model a simple GaAs PIN diode structure. Both the stimulated and spontaneous emission in the semiconductor are accounted for. The corresponding absorption of the light and the associated change in ... En savoir plus
During quenching of steel, austenite decomposes into phases such as ferrite, pearlite, bainite, and martensite. A common way to illustrate the phase transformation characteristics of a particular steel alloy is to use transformation diagrams. Two of the most commonly used diagram types ... En savoir plus
Conical antennas are useful for many applications due to their broadband characteristics and relative simplicity. In this example, we study the antenna impedance and radiation pattern as functions of frequency for a monoconical antenna with a finite ground plane and a 50 ohm coaxial ... En savoir plus
In this example, the Bergstrom–Boyce material model is used to capture the nonequilibrium behavior of carbon-black-filled chloroprene rubber under a strain history that alternates compression with relaxation. Results are verified against experimental and numerical results taken from ... En savoir plus
