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.
A beam splitter is used to split a single beam of light into two. One way of making a splitter is to deposit a thin layer of metal between two glass prisms. The beam is slightly attenuated within the layer, and split into two paths. In this example, the thin metal layer is modeled using ... Read More
This example was originally formulated by Albert Witarsa under Professor Bruce Finlayson’s supervision at the University of Washington in Seattle. It was part of a graduate course in which the assignment consisted of evaluating the potential of patents in the field of microfluidics ... Read More
Unwanted electrical arcing poses significant risks to the reliability and safety of electrical and electronic systems. To enhance predictive capabilities and deepen understanding of arc behavior, we present a comprehensive numerical model for simulating transient arc discharge phenomena ... Read More
The marine controlled source electromagnetics method (CSEM) for oil prospecting has emerged as a promising technique during recent years. This model demonstrates one variant of it. It uses a mobile horizontal 1 Hz electric dipole antenna that is towed 150 m above the sea floor. An array ... Read More
This tutorial shows how to model a slot die coating process with a power-law non-Newtonian fluid in one of the two phases. The model uses a two-phase flow phase-field method. Read More
This a continuation of the permanent magnet motor model available here . In this model, an heat transfer analysis has been performed to compute the temperature rise for various stator current and rotor speed. A detailed analysis on torque, and losses in iron and copper have then been ... Read More
This app demonstrates the following: Creating apps for small screens such as smartphones User-interface navigation with a top menu typically used on websites Dynamically hiding forms using card stacks to minimize the space required by the app Changing appearance by using different ... Read More
The Thermal Actuator Surrogate Model Application demonstrates how the computational speed can be increased with the use of a surrogate model. This app demonstrates the following: Adjusting input parameters via sliders, with near-instantaneous updates to the solution retrieved from the ... Read More
High Cycle Fatigue (HCF) of a spoke in a wheel rim is studied. As the wheel rotates, the stress histories in the structure will become nonproportional. The risk of fatigue is evaluated using the Findley criterion. Read More
Impedance tubes are used for estimating the surface impedance of various samples, for example, a layer of porous material used for sound insulation. This model shows how the five material parameters of the Johnson-Champoux-Allard model can be estimated from the pressure at two ... Read More
