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.
Electromagnetic scattering simulation for an object with continuous rotational symmetry can be performed in 2D axisymmetry instead of 3D to drastically reduce computational time and resources. This model shows how to simulate arbitrary plane wave incidence in 2D axisymmetric models by ... Read More
This proof-of-concept model showcases how to handle a Gaussian beam propagating in the negative y direction in 2D. The model includes several studies, including a parametric sweep, to cover a wide combination of settings describing the background Gaussian beam, such as settings for ... Read More
This model illustrates the working principle of a passive electrodynamic bearing. An electrically conducting rotor rotating in a magnetic field produced by a permanent magnets induces eddy currents on the conducting rotor. The eddy currents, in turn, produce a magnetic field that opposes ... Read More
A steel ball is pressed down against a rubber membrane. When the contact pressure exceeds a certain value, the two parts start sticking together. When the ball is retracted, the membrane is pulled upwards in the bonded region. During the retraction, the bond is partially broken. This ... Read More
This example shows how to model tissue ablation through applying RF radiation. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Study Radiofrequency Tissue Ablation Using Simulation". Read More
Surface plasmon polariton (SPP) as well as other types of surface electromagnetic waves is of great interest due to unique physical properties and application potentials. The models here demonstrate how to simulate SPP propagation and its frequency-momentum dispersion relation. The ... Read More
This model illustrates the working principle of an axial homopolar induction bearing. An electrically conducting rotor rotating in a magnetic field produced by a permanent magnets induces eddy currents on the conducting rotor. The eddy currents, in turn, produce a magnetic field that ... Read More
This model demonstrates how the sun causes 1.75 arcseconds of deflection for rays grazing the sun's surface as observed from the earth. Einstein predicted this value after refining his theory of relativity during World War I. Read More
This model calculates the DC breakdown voltage between parallel electrodes in air using a detailed charge transport approach. It is currently one-dimensional for simplicity but can be extended to other gases and dimensions. The results closely match experimental data found in the ... Read More
Stimulated Brillouin Scattering (SBS) describes a nonlinear interaction between light and sound. In optical fibers, SBS can be detrimental for power or communication purposes, but can be leveraged for sensing applications. The SBS gain spectrum quantifies the optic-acoustic mode ... Read More
