The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
This tutorial compares experimental data from the literature with a COMSOL model of a MOSCAP with interface traps (surface states). The Trap-Assisted Surface Recombination feature is used to simulate the effects of the trap charges and the processes of carrier capturing and emitting by ... Read More
Electrochemical glucose sensors use amperometric methods to measure the concentration of glucose in a sample. This example models the diffusion of glucose and ferri/ferrocyanide redox mediators in a unit cell of electrolyte above an interdigitated electrode. The sensor gives a linear ... Read More
This model simulates the isotropic compression of naturally structured and artificially structured clays using the Modified Structured Cam-Clay (MSCC) material model. The aim of the example is to reproduce the compression behavior given in a benchmark for four structured clays. Read More
Zinc-Silver oxide (Zn-AgO) batteries are used in different industries due to their high capacity per unit weight. In this work, discharge of a Zn-AgO battery is simulated using the Battery with Binary Electrolyte interface. The electrochemical reactions in the positive and negative ... Read More
This example performs a topological optimization for a Tesla microvalve for an oscillating pressure drop. A Tesla microvalve inhibits backward flow using friction forces rather than moving parts, and therefore the objective is to maximize the average flow rate. The design can be ... Read More
Some conventional three-port power dividers are resistive power dividers and T-junction power dividers. Such dividers are either lossy or not matched to the system reference impedance at all ports. In addition, isolation between two coupled ports is not guaranteed. The Wilkinson power ... Read More
A time-varying current induces a time-varying magnetic field. The magnetic field induces currents in neighboring conductors. The induced currents are called eddy currents. In this model, the phenomenon is illustrated by a time-harmonic field simulation as well as a transient analysis, ... Read More
Conical antennas are useful for many applications due to their broadband characteristics and relative simplicity. In this example, we study the antenna impedance and radiation pattern as functions of frequency for a monoconical antenna with a finite ground plane and a 50 ohm coaxial ... Read More
This example illustrates the modeling of vibration and noise in a 5-speed synchromesh gearbox of a manual transmission vehicle. A transient multibody analysis is performed to compute the gearbox vibration for the specified engine speed and external load. The normal acceleration of the ... Read More
This example demonstrates simulation of a turbulent flow in a geometry with an air filter. Porous material of the filter induces an abrupt pressure drop and drastic increase of turbulence level inside the filter. Read More
