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.
Using a Fluid-Solid Interaction multiphysics interface, the behavior of a spring-loaded ball check valve is studied under varying functional and reverse flow. The fluid force acting on the ball opens the valve at the opening pressure. In the case of a reversed pressure, the ball comes ... Read More
This example is a model of a continuous casting process. Liquid metal is poured into a mold of uniform cross section. The outside of the mold is cooled and the metal solidifies as it flows through. When the metal leaves the mold, it is completely solidified on the outside, but still ... Read More
This example shows how to compute the critical buckling load in the presence of dead loads. A truss tower is supported by pretensioned guys. The pretension load and gravity on the truss are considered as dead loads, while the vertical load applied at the top of the tower is considered ... Read More
High-power battery energy storage systems (BESS) are often equipped with liquid-cooling systems to remove the heat generated by the batteries during operation. This tutorial demonstrates how to define and solve a high-fidelity model of a liquid-cooled BESS pack which consists of 8 ... Read More
Tutorial model of an air-cooled battery energy storage system (BESS). The model includes conjugate heat transfer with turbulent flow, fan curves, internal screens, and grilles. It features several interesting aspects: Fully parameterized geometry, which can be modified for different ... 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
This model simulates a 16-level, first-order, focusing Fresnel lens with 50 µm diameter and 150 µm focal length. In one simulation, the Electromagnetic Waves, Frequency Domain interface computes the electric field in the Fresnel lens and the surrounding air domain extended to the focal ... Read More
Buckling is a structural instability that can cause a component to fail even when the material remains within the elastic regime. Therefore, determining the critical buckling loads and corresponding mode shapes can be important from a design perspective, even when the applied loads ... Read More
