Micromirrors are used in certain MEMS devices to control optic elements. This model of a vibrating micromirror surrounded by air uses the Thermoacoustic-Shell Interaction user interface to model the fluid-solid interaction, and it thus includes the correct viscous and thermal damping of ...

In general, there are two classes of ventilation: mixing ventilation and displacement ventilation. In displacement ventilation, air enters a room at the floor level and displaces warmer air to achieve the desired temperature. Heating sources in the room can include running electronic ... Mehr lesen
This model illustrates the working principle of an electrodynamic wheel (EDW) magnetic levitation system. EDW magnetic levitation system consists of rotating and/or translationally moving permanent magnet Halbach rotor above a passive conducting guideway/track. Eddy current is ... Mehr lesen
The model compare the electromagnetic force calculated by virtual work and maxwell stress tensor methods on the axial magnetic bearing. The forces is evaluated by studying the effect of a small displacement on the electromagnetic energy of the system. This is done by using the Magnetic ... Mehr lesen
This model is a benchmark problem from TEAM workshop (problem 15 part I, see https://www.compumag.org/wp/team/). The model simulates the behavior of a coil as it scans a conductive plate containing a defect (a crack). The computed coil parameters, which include change in resistance and ... Mehr lesen
In this model, two flat end mirrors are placed at a distance and a spherical lens is inserted in the middle of the cavity. 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 ... Mehr lesen
This model file was used for creating the plots featured in the blog post "How to Model Ion-Exchange Membranes and Donnan Potentials". Mehr lesen
Loudspeaker design is a challenging task, where the design objective is to achieve better sound quality without violating manufacturing and operational constraints. The quality of sound depends on many parameters; one of them is the ability to control, damp, and shift the diaphragm ... Mehr lesen
Recovery of precious metals in recycling of electronics, or extraction from ore, is usually performed through leaching of the metal into an aqueous phase. Precious metals require the use of an oxidant, and often, a complexant. In the case of gold, the cyanide anion (CN-) forms a soluble ... Mehr lesen
Dieses Tutorial demonstriert eine vollständige elektro-vibroakustische Analyse eines konzeptionellen elektrostatischen Lautsprechertreibers, der aus einer dünnen leitenden Kunststoffmembran besteht, die sich zwischen zwei perforierten Metallblechen, den Gittern oder Statoren, befindet. ...
