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 example simulates the thermodynamical evolution of moist air in an electronic box with the aim of detecting whether condensation occurs when the external environment properties change. The model imports measured data for the air temperature, pressure, and water vapor concentration. ... Read More
The suite of models examine the air cooling of circuit boards populated with multiple integrated circuits (ICs), which act as heat sources. Two possible cooling scenarios are depicted: vertically aligned boards using natural convection, and horizontal boards with forced convection (fan ... Read More
This example treats a pulmonary artery stenosis as a porous medium and demonstrates how to set up a model that combines free and porous media flow of a non-Newtonian fluid. The non-Newtonian behavior of blood is modeled using the Carreau model. Read More
This model shows how to set up a simulation of flow through a fractured reservoir. The reservoir includes a discrete fracture network (DFN), where the fractures have a randomized distribution of position, size, orientation and aperture. The model uses the Discrete Fracture Network Add ... Read More
This example introduces three different models for a lateral flow assay for the detection of coronavirus antibodies. These models are as follows: 3D model for studying possible symmetries in the spreading of the liquid sample in the test strip. The 3D model shows that the flow is ... Read More
This example demonstrates how to model a phase change and predict its impact on a heat transfer analysis. When a material changes phase, for instance from solid to liquid, energy is added to the solid. Instead of creating a temperature rise, the energy alters the material’s molecular ... Read More
Double-pipe heat exchangers, with their typical U-turn shape, are one of the simplest and cheapest type of heat exchangers used in the chemical process industry. This example studies the cooling of hot oil (130°C) by a cool oil (60°C) entering in counter-current. As the oils flow ... Read More
FSI analysis of a sports car side door and side rear view mirror. The model is based on large eddy simulation analysis of a sports car. The flow field is used for a structural analysis of the side mirror and side door to estimate the flow-induced vibrations. Read More
Electromagnetic heating is ideally suited for modeling in COMSOL Multiphysics. This model shows the area of hyperthermic oncology but the modeling issues and techniques are generally applicable to any problem involving electromagnetic heating. The purpose of this model is to compute the ... Read More
Drying of porous media is an important process in the food and paper industry among others. Many physical effects must be considered: fluid flow, heat transfer with phase change, and transport of participating liquids and gases. All of these effects are strongly coupled, and predefined ... Read More
