Dieses Modell stellt zwei Beispiele für die Topologieoptimierung des magnetischen Kreises eines Lautsprechertreibers vor. Eine erste Optimierung dient dazu, das Design eines nichtlinearen Eisenpolstücks und einer Deckplatte zu finden, die den BL-Faktor in der Ruheposition (kleine ... Mehr lesen
The layout of a district heating network is designed using topology optimization. Mehr lesen
This model simulates the propagation of two frequency bands in a photonic crystal with three ports. The crystal is initially symmetric, so that the two frequency bands are directly equally to either output port. The model optimizes the position of the pillars in order to make the two ... Mehr lesen
In this tutorial model, a step thrust bearing is shape optimized to maximize the bearing capacity. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be ... Mehr lesen
A solidly-mounted resonator (SMR) is a piezoelectric MEMS resonator formed on top of an acoustic mirror stack deposited on a thick substrate. This tutorial shows how to simulate an SMR in 2D. In this example, the eigenmodes were computed and the frequency response from 500 to 1200 MHz ... Mehr lesen
This model shows how to compute the anchor loss limited quality factor of a diamond disc resonator. The resonator is anchored to the substrate by a polysilicon post and power is transmitted to the substrate through the post. A perfectly matched layer is used to represent the essentially ...

This model shows how shape optimization can be used design the coils of an ICP reactor to obtain plasma uniformity. The reactor in study is a planar ICP with the coils distributed along the radial direction. The Optimization study step is used to find the best coil placement so that the ... Mehr lesen
This example demonstrates a benchmark test showing that Electric Currents in Layered Shells physics interface can be used to obtain the same results as when the model is solved with the Electric Currents interface based on a solid 3D structure. Mehr lesen
Microstrip filters can be fabricated directly on a printed circuit board (PCB) with a microstrip line going from the input to the output. Along the microstrip line there are a number of stubs of certain lengths and widths. The design of the filter involves choosing the impedance of the ... Mehr lesen
For an electrochemical reaction to occur, the reacting species usually needs to adsorb to the electrode surface before undergoing reduction or oxidation, after which the resulting product species desorbs back into the electrolyte. If the rate of adsorption or desorption is slow in ... Mehr lesen
