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.
A split ring resonator (SRR) has a band-stop frequency response that rejects a certain range of frequency. This type of SRR structure is popularly used as a resonator itself and can be combined periodically to build artificial meta-materials. In this model, a printed SRR on a ... Read More
Fiber composites are widely used in industrial applications. Compared to more traditional metallic engineering materials, fiber composites often have superior specific stiffness and strength properties, and they are often more corrosion resistant. Also, properties like strength, ... Read More
This model analyzes lightning surges in an offshore wind farm. When a lightning strike with a current of 20 kA hit one wind turbine, the induced electric fields in adjacent wind turbines were computed. Read More
This example simulates turbulent flow around a sports car traveling at a speed of 180 km/h using Large Eddy Simulations (LES). Read More
The Monte Carlo simulation of flow in a turbomolecular pump can be greatly simplified if the mean radius of the blades is much greater than the spacing between them. Under these conditions, the rotating blades of the pump can be approximated as an infinite row of blades having only ... Read More
This example illustrates the principle of wet chemical etching for 2D geometry under laminar flow. The purpose of this tutorial is to examine how the copper substrate material is depleted and how the cavity shape evolves during the wet etching process. Wet chemical etching is ... Read More
This model treats the free convection of argon gas within a light bulb. It shows the coupling of heat transport (conduction, radiation and convection) to momentum transport (non-isothermal flow) induced by density variations caused by temperature. COMSOL Multiphysics model makes it ... Read More
Loudspeaker design is a challenging task, where the design objective is to achieve better sound quality without violating manufacturing and operational constraints. The quality of sound depends on many parameters; one of them is the ability to control, damp, and shift the diaphragm ... Read More
This example models the flow in a 90-degree pipe elbow. The flow is simulated using the k-omega turbulence model. The result is compared to engineering correlations. Read More
The demand for phased array antennas increases not only for the traditional military industry but also in commercial areas such 5G mobile network platforms, Internet of Things (IoT), and satellite communication applications. This example shows how to design a phased array with a beam ... Read More
