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 compares moisture transport within two types of anisotropic porous medium. The first component defines a layered structure. The structure alternates between layers with high and low moisture diffusivity. So the moisture spreads more easily along the layers than transversely. ... Read More
This tutorial model compares the results between a domain approach and the Thin Moisture Barrier feature to simulate the moisture transport in a wall with a vapor barrier. The Thin Moisture Barrier feature neglects diffusion, two studies are proposed, a first one where diffusion is ... Read More
This model simulates a plasma at medium pressure (2 torr) where the plasma is still not in local thermodynamic equilibrium. At low pressures the two temperatures are decoupled but as the pressure increases the temperatures tend towards the same limit. Read More
This example investigates the electrical performance of a cascaded cavity filter operating in the millimeter-wave 5G band with temperature changes. The thermal variations result in structural deformations of the structure. Thus, the resonant frequencies of the filter elements (cavities) ... Read More
In this example, a dynamic analysis of a three-cylinder reciprocating engine is performed to investigate stresses generated during operation, thereby permitting identification of the critical components. Demand for high power output relative to the weight of the engine requires careful ... Read More
These tutorial models show how to use the tools to assist with defining surface-to-surface radiation models. In the first model, radiation direction symbols are used to find an unexpected configuration where the opacity is not correctly defined. In the other, the topology check ... Read More
This model investigates the electrical and thermal characteristics of an inductively coupled plasma torch at atmospheric pressure. The discharge is assumed to be in local thermodynamic equilibrium. Read More
This example shows how to compute deformations caused by secondary creep in a turbine stator blade. The creep rate is highly influenced by temperature, and the deformation and stress relaxation is thus controlled by the temperature field. Read More
This tutorial model solves for an inductively coupled plasma reactor with RF bias (also known as ICP/CCP reactors) in a mixture of argon/chlorine. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. Read More
This example computes the power losses in a lithium-ion battery when exposed to high current pulses in a hybrid pulse power characterization (HPPC) test. Power loss contributions stemming from different phenomena are analyzed, as well as the total power losses pertaining to the ... Read More
