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 tutorial demonstrates how to partition a 3D part to create a swept mesh. The example explores different strategies for partitioning the geometry, and demonstrates how to combine hexahedral and tetrahedral meshes. Read More
At the resonance frequency, the capacitive coupling between the turns causes the impedance of a coil to transition from inductive to capacitive. This application analyzes the resonance of a 5 turn spiral coil of copper equipped with a thin epoxy varnish insulation layer. The capacitive ... Read More
Hydrogen embrittlement refers to the degradation of metal ductility due to the absorption of hydrogen. The metal becomes more brittle and thus cracks might initiate at lower stress levels. It is important to estimate hydrogen concentration and the speed at which it diffuses into the ... Read More
This example demonstrates how to use the Electrostatic interface to calculate the surface electric field of a typical high-voltage insulator. It is shown that the inhomogeneity and the maximum of the surface electric field are greatly reduced with the installation of the grading rings. ... Read More
In this example, a random vibration test of electronic equipment is simulated. Three analyses are performed, one for acceleration in each global direction. Accelerations in the components and forces in clamping bolts are evaluated. 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
The tonpilz (sound mushroom) piezoelectric transducer is a transducer for relatively low frequency, high power sound emission. The transducer consists of piezoceramic rings stacked between massive ends and pre-stressed by a central bolt. The tail and head mass lower the resonance ... Read More
Electromagnetic analysis of a 400kVA, 15kV/400V three-phase power transformer with Y-d connection and multiple primary and secondary coils with hundreds of turns. The model features the standard open- and short-circuit test in 2Daxi and 3D simulations to estimate electrical quantities ... Read More
This model example simulates an air-cooled cylindrical 18650 lithium-ion battery during a charge-discharge cycle, followed by a relaxing period. A lumped (0D) cell model is used to model the battery cell chemistry, and a two-dimensional axi-symmetrical model is used to model the ... Read More
This tutorial model solves for a hydrogen plasma created in a microwave cavity. The model computes the fluid flow and gas heating self-consistently. Read More
