In a gearbox, vibrations due to gear rattling and bearing misalignment are well known sources of noise. In this example, two shafts connected through a pair of gears are considered. The shafts are supported on roller bearings at their ends. Initially, the driven shaft is unloaded and the ... Mehr lesen
The Free Molecular Flow interface, available in the Molecular Flow Module, is an efficient tool for modeling extremely rarefied gases when the gas molecules move much faster than any geometric entities in the domain. For turbomolecular pumps, in which the blades move at speeds comparable ... Mehr lesen
The Particle Tracing for Fluid Flow interface is used to compute the erosion of a pipe bend. The amount of material lost is computed using different erosion models. Mehr lesen
This model shows how shape optimization can be used to design an acoustic demultiplexer. A demultiplexer is a data distributing device, in this case it will distribute acoustic energy. The geometry consists of a circular domain with one input port and two output ports. The domain has the ... Mehr lesen
In this example, wear of the friction material in a disc brake is studied. Quasistatic friction forces are prescribed from simple kinematic considerations. The geometry of the brake pad is continuously updated to account for the material removal due to wear following the well-known ... Mehr lesen
This model simulates an LED that emits in the infrared part of the electromagnetic spectrum. The device structure is made up of a single p-n junction formed by a layer of p-type doping near the top surface of an otherwise n-type wafer. This kind of device geometry is simple and cheap to ...

This tutorial example models the currents and the concentration of dissolved metal ions in a battery (corrosion cell) made from an orange and two metal nails. This type of battery is commonly used in chemistry lessons. Instead of an orange, lemons or potatoes can also be used. Mehr lesen
AT cut quartz crystals are widely employed in a range of applications, from oscillators to microbalances. One of the important properties of the AT cut is that the resonant frequency of the crystal is temperature independent to first order. This is desirable in both mass sensing and ... Mehr lesen
In diesem Tutorial werden die akustischen Eigenschaften eines Cerumenschutzes analysiert. Ein Cerumenschutz ist ein kleines perforiertes Netz, das zum Schutz des Hörers (des Miniaturlautsprechers in einem Hörgerät) bei Hörgeräten mit Receiver-in-the-Ear (RITE) oder Receiver-in-Canal ... Mehr lesen
This model defines a zero-gap alkaline water electrolyzer, where oxygen and hydrogen gas are evolved in porous gas diffusion nickel felt electrodes, placed adjacent to a porous separator (diaphragm). The geometry defines a unit cell of an electrolyzer stack, in turn comprising two full ... Mehr lesen
