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.
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 study simulates the thermal behavior of a computer Power Supply Unit (PSU). Most of such electronic enclosures include cooling devices to avoid electronic components to be damaged by excessively high temperatures. In this model, an extracting fan and a perforated grille cause an air ... 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
This example shows how to set up multiple sandwiched thin layers with different thermal conductivities in two different ways. First, the composite is modeled as a 3D object. In the second approach the Thin Layer boundary condition with the thermally thick option is used to avoid ... Read More
This example studies the stationary state of free convection in a cavity filled with air and bounded by two vertical plates. To generate the buoyancy flow, the plates are heated at different temperatures, set in a range to keep the flow laminar. Read More
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
Deposition of metallic lithium on the negative electrode in preference to lithium intercalation is known to be a capacity loss and safety concern for lithium-ion batteries. Harsh charge conditions such as high currents (fast charging) and/or low temperatures can lead to lithium plating. ... Read More
The heat exchanger in this tutorial model contains a dynamic wall with an oscillating wave shape. The deformation induces mixing in the fluid and reduces the formation of thermal boundary layers. Hence, it increases heat transfer between the walls and the fluid. In addition, the wave ... Read More
Thermal energy storage units are used to accumulate thermal energy from solar, geothermal, or waste heat sources. The simplest units are built from water tanks, often found in households, where the solar energy is stored as sensible heat. The thermal capacity of these tanks can be ... Read More
This example studies the stationary state of free convection in a cavity filled with water and bounded by two vertical plates. To generate the buoyancy flow, the plates are heated at different temperatures, bringing the regime close to the transition between laminar and turbulent. To ... Read More
