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.
Fluence rate is a key parameter for ultraviolet (UV) water purifier. It describes the amount of radiation that pathogens absorb and is then directly related to the disinfection level of the purifier. The aim of this example is to demonstrate the fluence rate calculation with the ... Read More
The model illustrate the technique to calculate the magnetic stiffness in a 3D geometry of a permanent magnet axial magnetic bearing. The Magnetic Fields physics is used to model the bearing and compute the magnetic forces. The Deformed Geometry and Sensitivity physics are used to ... Read More
This model shows the workflow to define a transfer orbit trajectory with user defined orbit option. The direct solar, albedo, and Earth radiative thermal loads are analyzed during the transfer from low Earth orbit to geostationary orbit. Read More
Many important processes in the mesoscale can be described by phase-field models. One of the oldest phase-field problems is the spinodal decomposition. Several standardized benchmark problems have been developed by the phase-field community. In this entry, these problems are solved using ... Read More
In this example, the etching of silicon in a CF4/O2 plasma reactor is studied using a global model. Parametric sweeps for ion energy and oxygen mole fraction are computed. Read More
Bearing clearances should be kept minimum to avoid non-synchronous vibration of a rotor. However, a tight clearance reduces the durability of the bearing. This example illustrates modeling of the vibration induced by nonlinear contact for different radial clearances. It is shown that ... 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 example simulates Trichel pulses produced by negative corona discharge under a point-to-plate configuration. The electron density and the electric field are obtained, as well as the discharge current. The discharge current clearly shows the pulsating characters. Each current pulse ... Read More
This model analyzes the scattering of a plane propagating modulated Gaussian pulse off a submarine hull. The scattered field and the spatial response are also determined. The model uses the Pressure Acoustics, Time Explicit interface to model this large acoustic model in the time domain. ... Read More
This model computes the specific acoustic radiation impedance of a very small circular vent in a flanged configuration. The model includes thermoviscous losses. The radiation impedance is fitted using a simple RL circuit which gives a simple lumped representation. The results are used ... Read More
