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 model demonstrates how to estimate the material parameters of a viscoplastic Bergstrom–Boyce model suitable for nonequilibrium modeling of rubber-like materials. The data used for parameter estimation consists of cyclic uniaxial tension and compression tests at two ... Read More
In an alkaline electrolyzer stack, all cells share the same electrolyte. As a result of all cells being in ionic contact, parasitic shunt currents flow between the cells through the manifolds and the electrolyte channels, on both the inlet and outlet side. This example models a ... Read More
This model captures the dynamic resistive switching behavior of an oxide-based memristor. The device features a thin metal oxide layer sandwiched between two metal electrodes. When a voltage is applied, oxygen vacancies within the oxide layer migrate, acting as charge carriers and ... Read More
In modeling of transport by diffusion or conduction in thin layers, we often encounter large differences in dimensions of the different domains in a model. If the modeled structure is a so-called sandwich structure, we can replace the thinnest geometrical layers with a thin layer ... Read More
This tutorial shows how to model a miniaturized magnetostrictive antenna developed for use inside living cells. The stress in the antenna, the magnetic flux density, the current density, and the displacement of the tip of the device are investigated at the resonance frequency. Read More
This tutorial demonstrates the operation of a gyroscope based on design provided by Dr. James Ransley at Veryst Engineering, LLC. The model uses the Electromechanics coupling with the mixed finite element formulation in the Electrostatics interface. Read More
The following example solves a pure conduction and a free-convection problem in which a vacuum flask holding hot coffee dissipates thermal energy. The main interest is to calculate the flask's cooling power; that is, how much heat it loses per unit time. This tutorial model treats the ... Read More
When several components are to be electroplated they are typically mounted on a rack in the electroplating bath. An important aspect is then achieving a uniform thickness of the plated layer for all components mounted on the rack. This example model allows for investigating the effect ... Read More
A thermoacoustic engine is a device with no moving parts that can generate acoustic energy from temperature gradients within the engine. It uses the relationship between the movement of oscillating air and the temperature changes in the air compressed and expanded by the acoustic waves. ... Read More
This example shows how to set up a glacier flow model in principle, containing several important aspects of glacier modeling: The creation of the 2D geometry, the modeling of non-Newtonian flow, and the implementation of basal sliding. In this example, two different glacier types, a cold ... Read More
