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.
Recovery of precious metals in recycling of electronics, or extraction from ore, is usually performed through leaching of the metal into an aqueous phase. Precious metals require the use of an oxidant, and often, a complexant. In the case of gold, the cyanide anion (CN-) forms a soluble ... Read More
This tutorial demonstrates how to use stationary polarization data to perform parameter estimation of a polymer electrolyte membrane fuel cell (PEMFC) model. The model, defining a 5-layer membrane electrode assembly (MEA) is two-dimensional and includes electronic and ionic charge ... Read More
This example demonstrates how to plot the interference pattern from the combination of two rays with slightly different optical path length. A simple Michelson interferometer is used to achieve a change of optical path length by slightly moving one of the mirrors. Read More
The Marangoni effect results in a slip velocity in the tangential direction on a fluid/fluid interface due to gradients in the surface tension coefficient. When the surface tension coefficient is constant, a two-fluid system may exist in static equilibrium. This is because the surface ... Read More
Although initially invented to be used in printers, inkjets have been adopted for other application areas, such as within the life sciences and microelectronics. Simulations can be useful to improve the understanding of the fluid flow and to predict the optimal design of an inkjet for a ... Read More
This example of turbulent flow in a partially baffled turbulent mixer with a three-bladed impeller shows how to set up the Rotating Machinery, Turbulent Flow interfaces from the Mixer Module with a Level Set method for free surface flow in a rotating geometry. A time-dependent simulation ... Read More
This example simulates an oil droplet rising through a suspension. The suspension is initially stratified, with a dense layer between two clear layers. The droplet is initially located in the bottom clear layer. The particles in the suspension start to sediment toward the bottom of the ... Read More
This tutorial shows how to model transport of the individual ions in a salt melt comprising two binary salts, where the transport equations are defined using concentrated solution theory. The example model defines a molten carbonate fuel cell (or electrolyzer), with a 1D-model geometry ... Read More
Emulsions consist of small liquid droplets immersed in an immiscible liquid and widely occur in the production of food, cosmetics, fine chemicals, and pharmaceutical products. The quality of the product is typically dependent on the size of the droplets. Simulating these processes can ... Read More
