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 example models the casting process of a metal rod from liquid to solid state using the Non-Isothermal Flow multiphysics interface, which combines heat transfer and fluid flow. The model describes the fluid and solid flow and heat transport, including the phase transfer from melt to ... Read More
Emulsions consist of small liquid droplets immersed in an immiscible liquid and widely occur in the production of food, cosmetics, fine chemicals, and pharmaceutical products. The quality of the product is typically dependent on the size of the droplets. Simulating these processes can ... Read More
Modeling the electrical activity in cardiac tissue is an important step in understanding the patterns of contractions and dilations in the heart. The heart produces rhythmic electrical pulses, which trigger the mechanical contractions of the muscle. A number of heart conditions involve ... Read More
This model shows how to simulate a capacitively actuated surface micromachined accelerometer, using the Electromechanics Interface. It is based on a case study from the book Microsystem Design by Stephen D. Senturia (Kluwer Academic Publishers, 5th Edition, 2003, pages 513-525). Read More
The electrochemical cell shown in this model can be regarded as a unit cell of a larger wire-mesh electrode that is common in many industrial processes. One of the most important aspects in the design of electrochemical cells is the current density distributions in the electrolyte and ... Read More
This model calculates the DC characteristics of a simple MOSFET. The drain current versus gate voltage characteristics are first computed in order to determine the threshold voltage for the device. Then the drain current vs drain voltage characteristics are computed for several gate ... Read More
In fuel cell power generators, a steam reformer unit typically produces the hydrogen needed for the cell stack. This example illustrates the modeling of a steam reformer. The reformation chemistry occurs in a porous catalytic bed where energy is supplied through heating tubes to drive ... Read More
In this study, the compressible turbulent flow through a supersonic ejector is modeled using the High Mach Number Flow interface in the CFD Module. Ejectors are simple mechanical components used for a wide range of applications, including industrial refrigeration, vacuum generation, gas ... Read More
In its simplest form, an optical ring resonator consists of a straight waveguide and a ring waveguide. The waveguides are placed close to each other, making the light affect each between the two structures. If the propagation length around the ring is an integral number of wavelengths, ... Read More
A strong permanent magnet is placed close to a clamped thin plate made of iron. The magnetic force causes the plate to be deflected. This example studies the plate's elastic deformation and stress. The deformation of the plate has an influence on the distribution of the magnetic field. ... Read More
