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 model demonstrates the use of optical tracing for studying optically large gradient-index structures with anisotropic optical properties. Additionally, the model introduces a smoothing technique for handling discontinuities of refractive index on curved surfaces, which are typical ... Read More
The common electroanalytical method of exhaustive amperometric detection in a microscopic thin layer is modelled as a 1D-symmetric diffusion problem. The simulated result agrees with the analytical Cottrell equation at short times, and deviates as expected at long times when the ... Read More
Use this app to validate that the default settings correctly submit jobs to a cluster. These default settings are taken from the preferences. The app allows you to override the default cluster settings, test modifications to the current setup, and test different settings for connecting ... Read More
This model compares the numerical and analytical solutions for the capacitance matrix of two non-concentric spheres. It also illustrates the relation between the Maxwell capacitance matrix and the mutual capacitance matrix. Learn more about this model in the blog post "How to Calculate ... Read More
This model simulates an electrodeless lamp with argon/mercury chemistry. The low excitation threshold for mercury atoms means that even though the mercury is present in small concentrations, its behavior dominates. There is strong UV emission from the plasma at 185 nm and 253 nm. The UV ... Read More
The use of Aluminum (Al) isolator is a commonly employed mitigation strategy for galvanic corrosion between magnesium alloy (Mg) and mild steel (MS). The present model demonstrates the effect of Al isolator thickness on galvanic corrosion severity using a parametric study. The electrode ... Read More
One way to design a filter is to use the element values of well-known filter prototypes, such as maximally flat or equal-ripple low-pass filters. It is easier to fabricate a distributed element filter on a microwave substrate than a lumped element filter, since it is cumbersome to find ... Read More
The pyrolysis of a centimeter-sized wood particle presents a fully coupled multiphysics problem with mass transfer, fluid flow, and heat transfer. This example model consists of two parts. The first part demonstrates how to set up a model describing the pyrolysis of a porous, ... Read More
This example solves the problem of finding the optimal thickness profile of a flywheel, so that the moment of inertia is maximized without increasing the mass or the maximum stress in the flywheel. Read More
This model demonstrates the use of boundary element method in the Electromagnetic Waves, Boundary Element interface to model an optical Yagi-Uda antenna. The antenna is driven by an electrical point dipole, which is implemented through the background field. The field distribution around ... Read More
