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 app demonstrates the following: Parameterized geometries Visualizing material appearance, color, and texture Multiple plots in the same window to visualize the results Options to visualize the results with different views using check boxes Microstrip patch antenna arrays are ... Read More
This tutorial shows how to set up a multi-element objective lens. The chosen lens is a Petzval lens with field flattener described in 'Fundamental Optical Design', by M. Kidger, 2001, pg 192. The tutorial demonstrates how to include a geometric sequence using the 'Spherical General Lens ... Read More
This tutorial example models the currents and the concentration of dissolved metal ions in a battery (corrosion cell) made from an orange and two metal nails. This type of battery is commonly used in chemistry lessons. Instead of an orange, lemons or potatoes can also be used. Read More
The dipole antenna is one of the most straightforward antenna configurations. It can be realized with two thin metallic rods that have a sinusoidal voltage difference applied between them. The length of the rods is chosen such that they are quarter wavelength elements at the operating ... Read More
This tutorial demonstrates the Lumped Battery interface for modeling capacity loss in a battery. A set of lumped parameters are used to describe the capacity loss that occurs due to parasitic reactions in the battery, assuming no knowledge of the internal structure or design of the ... Read More
A plane electromagnetic wave propagating through free space is incident at an angle upon an infinite dielectric medium. This model computes the reflection and transmission coefficients and compares the results to the Fresnel equations. Read More
This example treats the modeling of electroosmotic flow in porous media. The system consists of a compartment of sintered porous material and two electrodes that generate an electric field. The cell combines pressure and electroosmotic driven flow. The equations that are solved are the ... Read More
This benchmark models two-phase flow in a porous medium in 1D, where the flow can be analytically described by the Buckley-Leverett equation. Read More
This example simulates particles in a range of sizes that move through different levels of a cascade impactor. A cascade impactor is an inertial particle separation device consisting of multiple levels separated by collecting plates and nozzles. Particle-laden air enters from the top ... Read More
This verification model uses the Electromagnetic Waves, Boundary Elements interface to simulate the RCS of perfectly conducting sphere. The simulated result is compared to analytical calculation to verify the accuracy. Read More
