This simple tutorial model shows how to set up a parametric sweep over a number of frequency bands (octaves or 1/3 octaves) and remesh once per band. A frequency sweep is performed within each band, which now has an adequate mesh resolution. This approach saves some computational effort ... Mehr lesen
In this model, a linear magnetic gear system with a gear ratio of 11:4 is modeled. The liner magnetic gear is assumed to be infinitely long with the modular structure that is repeating on either side. Only a single modular section is modeled by using the customized linear periodic ... Mehr lesen
In a diode or a transistor, when a p-n junction is reverse-biased (the p-side is connected to a lower potential than the n-side), ideally, no current should flow. However, due to minority carriers (electrons in the p-side and holes in the n-side), a small current, known as the reverse ... Mehr lesen
This model is used in the blog post "Why Do Golf Balls Have Dimples?". The trajectory of a golf ball is compared to the trajectory of a smooth ball using the Events interface and a system of ODEs in a 0D component. Mehr lesen
One of the ways we can simplify and reduce the size and computational complexity of a finite element model is by using any symmetries present in a model. In this entry, you can find three practical examples highlighting how to exploit symmetries in RF or wave optics modeling. They all ... Mehr lesen
Full scale, time dependent model of an offshore oil platform jacket utilizing sacrificial anodes, coating breakdown and calcareous deposits on steel surfaces. The tutorial aims to meet some of the common questions for simulations in the oil and gas industry. This of course applies to ... Mehr lesen
This model demonstrates how to solve an ordinary differential equation for the motion of a spacecraft about a planet. In addition to computing the path, it is possible to use several results presentation features to make interesting visualizations. For a full description of this model, ... Mehr lesen
This local demo database for the Model Manager contains an imported copy of the Application Library models in COMSOL Multiphysics® version 6.0 and above. You can add this database from COMSOL Multiphysics® by selecting Download Demo Database for Model Manager from the ... Mehr lesen
This tutorial shows how to simulate coupled heat and moisture transport in a wall made of a load bearing and an insulation layer. Moisture and temperature conditions vary with time on both sides of the wall and rain loading is included. The 1D model is a benchmark test defined in ... Mehr lesen
Topology optimization is associated with extreme design freedom which can yield extreme performance. The designs can be easier to manufacture by using milling constraints, at some cost to the performance. This example considers the case of a torsion sphere which is known to feature a ... Mehr lesen
