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 models electrocoating of paint onto a car door in a time-dependent simulation. The deposited paint is highly resistive which results in lowered local deposition rates for coated areas. A primary current distribution in combination with a film resistance model is used to ... Read More
This example demonstrates how to use the Uncertainty Quantification Module by running a series of uncertainty quantification studies for a steel bracket. This type of bracket can be used to install an actuator that is mounted on a pin placed between the two holes in the bracket arms. ... Read More
This example demonstrates how to optimize the thickness of a microelectromechanical systems (MEMS) mirror coating material for maximum reflectivity. To reduce the simulation time, a Layered Impedance Boundary Condition is used to model the thin coating material on top of the metallic ... Read More
This model simulates Gaussian to Laguerre Gaussian beam shaping with the Beam Envelopes interface, the unidirectional wave formulation. The input beam is a focusing Gaussian beam with a topological spiral phase. It is known that this phase mask converts a Gaussian beam to a donut ... Read More
This example is a benchmark problem for simulating phase change in porous media. It studies the melting process of an ice inclusion within porous media and therefore demonstrates how to couple Darcy's Law with the Heat Transfer in Porous Media interface including phase change. Read More
A fuel cell stack operates at temperatures just below 100 °C, which means that it has to be heated at start-up. The fuel cell stack consists of unit cell of anode, membrane, and cathode connected in series through bipolar plates. This study presents a model that couples the thermal and ... Read More
This example reproduces a NAFEMS benchmark in which a plate with an angle crack is subjected to tensile loading. The J-integral is calculated and the stress intensity factors for Mode I and Mode II are compared to the benchmark results for several crack angles. Read More
A strong permanent magnet is placed close to a clamped thin plate made of iron. The magnetic force causes the plate to be deflected. This example studies the plate's elastic deformation and stress. The deformation of the plate has an influence on the distribution of the magnetic field. ... Read More
The Whirling of a Uniform Shaft tutorial model shows you how to perform a transient analysis of a uniform shaft under gravity. The shaft is supported by two hydrodynamic bearings at its ends. The gyroscopic effect causes the rotor to whirl about its initial axis and the rotor eventually ... Read More
In this example, the External Stress feature in the Solid Mechanics interface is used to provide the material model with the nonsymmetric stress required in the design of an elastic invisibility cloak. The cloak is a domain with special material properties aimed at shielding a region of ... Read More
