This model simulates convective heat transfer in a channel filled with water. To reduce memory requirements, the model is solved repeatedly on a pseudo-periodic section of the channel. Each solution corresponds to a different section, and before each solution step the temperature at the ... Mehr lesen
This example models the radiation of fan noise from the annular duct of a turbofan aeroengine. When the jet stream exits the duct, a vortex sheet appears along the extension of the duct wall due to the surrounding air moving at a lower speed. The near field on both sides of the vortex ...

Cross-coupled forces present in a hydrodynamic bearing often act as a negative damping in a rotor. Near the critical speed, this may lead to uncontrolled vibration of the turbocharger causing a risk of bearing failure. In this example, the influence of the cross-coupling forces on the ...

In the search for weight reduction, the cross-section of an eyeglass frame is continuously reduced. The thin section over the nose transfers the entire load between the two halves. This example predicts the fatigue life using the combined Basquin and Coffin-Manson model when eyeglasses ... Mehr lesen
A thin-walled frame with a central cutout is subjected to a random load. Although the stresses are far below the yield level of the material, damage accumulates over the load history. The Rainflow counting algorithm is used to define the load scenario and Palmgren-Miner linear damage ... Mehr lesen
This app allows to calculate the absorption coefficient and surface impedance of a sound absorbers for normal and random incidences. The computed quantities can be used when setting up boundary conditions in a Pressure Acoustics, Frequency Domain model or a Ray Acoustics model. The ... Mehr lesen
Die Ersatzmodell-App Thermischer Aktuator zeigt, wie Sie die Berechnung für Multiphysik-Analysen mithilfe eines Ersatzmodells beschleunigen können. Ein Ersatzmodell ist ein einfacheres, in der Regel rechnerisch günstigeres Modell, das zur Annäherung an das Verhalten eines komplexeren und ... Mehr lesen
The metal-silicon-oxide (MOS) structure is the fundamental building block for many silicon planar devices. Its capacitance measurements provide a wealth of insight into the working principles of such devices. This tutorial constructs a simple 1D model of a MOS capacitor (MOSCAP). Both ... Mehr lesen
A 2D model of a steel bar is used to simulate oil quenching from an austenitic state. Both diffusive and displacive phase transformations are used, and the phase composition is computed in the radial direction of the bar. Mehr lesen
In this example, it is demonstrated how to extend the built-in linear elastic material model to a Cosserat material through the addition of microrotation degrees of freedom. A cylindrical bar under pure torsion is analyzed and the effect of the Cosserat length scale parameter on the ... Mehr lesen
