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.
Heating of an object from alternating regions is one example where the modeling technique of activating and deactivating physics on domains can be useful. This model demonstrates how you can apply this technique using LiveLink™ for MATLAB®. Read More
Polymer hydrogels consist of a crosslinked network of long-chained polymers that has imbibed a large number of solvent molecules. Such materials are used in many biomedical applications, such as targeted drug delivery, tissue engineering, and stimuli-sensitive actuators. This benchmark ... Read More
Non-isothermal non-Newtonian flow in an internal mixer for rubbers and polymers. The Carreau model is used including thermal effects for the viscosity. Read More
Non-Newtonian fluids have complex flow characteristics that vary with shear rate, making their behavior in porous materials difficult to predict. Pore scale modeling captures these flow patterns at a microscopic level, helping derive properties for macroscale use. This model ... Read More
A Gaussian beam is incident on a 45-degree thin-film stack embedded in glass material prisms. The thin-film stack is designed from alternating high and low refractive index materials. The wave will be refracted at the Brewster angle at each internal interface. Thus, mainly p-polarized ... Read More
This model simulates convective heat transfer in a channel filled with water. To reduce memory requirements, the model is solved repeatedly on a pseudo-periodic section of the channel. Each solution corresponds to a different section, and before each solution step the temperature at the ... 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
This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in SOLIDWORKS® by using the LiveLink™ interface with a parametric sweep. Read More
This app demonstrates the following: Geometry parts and parameterized geometries Using tables for user input parameters Visualization on a 2D cross-section of a 3D geometry Improved visualization and user experience when a geometry object (the air object) is hidden. Induction heating ... Read More
Flow over a cavity and the tonal noise generated is a typical flow noise source in piping systems that have valves and other cavities. This tutorial model represents a simple case of cavity flow noise in a ducted system. The model is set up based on an example from Lafon et al. The ... Read More
