Ein klassisches Benchmark-Beispiel in der Elektromagnetik ist die Bestimmung der Resonanzfrequenz und des Gütefaktors eines Hohlraums mit verlustbehafteten Wänden. Hier wird gezeigt, dass die Modelle für rechteckige, zylindrische und kugelförmige Hohlräume mit den analytischen Lösungen ... Mehr lesen
This model solves the Boltzmann equation in two-term approximation for a mixture of nitrogen and oxygen representing a background gas of dry air. Electron transport coefficients and source terms are computed by suitable integration of the electron energy distribution function over ... Mehr lesen
A gate-all-around MOSFET consists of a nanowire with a gate electrode wrapped around the circumference. Since the entire nanowire forms the channel, this configuration provides the best possible electrostatic control of the channel and offers a good candidate for the miniaturization of ... Mehr lesen
This entry is a compilation of some examples from DIN EN 1991-1-2 (Actions on structures exposed to fire). Models that are included: 1. Cooling (HT) 2. Heating (HT) 3. Heat transfer through multiple layers (HT) 4. Thermal elongation (SME, thermal stress) 5. Thermal expansion (SME, HT, ... Mehr lesen
This benchmark model computes the valence band structure of an unstrained and a strained bulk GaN wurtzite crystal, as a tutorial for users who wish to set up multiple wave function components with the Schrödinger Equation interface. The model follows the formulation given in the ... Mehr lesen
The model is defined as a benchmark case in norm 15026:2007 annex A. The purpose of the model is to calculate the temperature and moisture profiles at different times after a change in the external conditions (temperature and relative humidity) inside a wall material (kind of concrete). ...

This model is an introduction to defining and verifying a satellite orbit, and computing the solar, albedo, and Earth infrared thermal loads. A 1U CubeSat is in a circular orbit at 400km altitude, inclination of 50°, and longitude of ascending node of 0°. The satellite is rotating slowly ... Mehr lesen
This example extends the corrosion protection system analysis of the single oil platform example by modeling the influence of multiple oil platforms placed in an array. The use of the Current Distribution on Edges, BEM interface significantly reduces the problem size and computational ... Mehr lesen
The model includes a compilation of benchmark examples included in the text book: Shape Memory Alloys: Modeling and Engineering Applications. D. Lagoudas Ed. Springer 2008. The model uses the Souza–Auricchio model and shows the thermomechanical properties of a NiTi alloy sample ... Mehr lesen
A waveguide-type structure can be fabricated on a substrate by adding vias between the microstrip line and the ground plane. Such a device will behave as a high-pass filter and is attractive because it is easy to fabricate. A model is set up that shows the S-parameters as a function of ... Mehr lesen
