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 presents the averaging models available within the Heat Transfer in Porous Media interface, used to compute the effective thermal conductivity, when the local thermal equilibrium assumption is made. The models are compared for porosities ranging from 0 to 1, and for a ... Read More
Many piezoelectric materials are ferroelectric. Ferroelectric materials exhibit nonlinear polarization behavior, such as hysteresis and saturation at large applied electric fields. In addition, the polarization and mechanical deformations in such materials can be strongly coupled due to ... Read More
In food industries, microwave heating is gaining attention over a conventional heating treatment because of several advantages such as precise process control, speed of heating, fast turn-on and turn-off time, etc. In this model, a high directional Yagi-Uda antenna is used to heat up ... Read More
This example demonstrates how to plot the interference pattern from the combination of two rays with slightly different optical path length. A simple Michelson interferometer is used to achieve a change of optical path length by slightly moving one of the mirrors. Read More
This example models galvanic corrosion between two different phases in a magnesium alloy for a representative cross-sectional microstructure configuration. The Level Set interface is used here to model dissolution of a constituent phase leading to topological changes. The electrode ... Read More
Tutorial model of electroplating. The model uses secondary current distribution with full Butler-Volmer kinetics for both anode and cathode. The thickness of the deposited layer at the cathode is computed as well as the pattern caused by dissolution of the anode surface. Read More
This example demonstrates how to use temperature dependent materials within the Nonlinear Structural Materials Module. A large container holds pressurized hot water. Several pipes are attached to the pressure vessel. Those pipes can rapidly transfer cold water in case of an emergency ... Read More
This conceptual example shows how to handle a transient contact problem with stick-slip friction transition. A soft hollow pipe subjected to gravity is released at the top of a halfpipe. The pipe motion varies between sliding and rolling, depending on its position in the halfpipe and its ... Read More
This model illustrates the operation of a swashplate mechanism used in helicopters to translate the input of helicopter flight control into the motion of the rotor blades, and hence controls the orientation of the rotor blades. In this model, the rotor blades are modeled as either rigid ... Read More
A spiral slot antenna provides a conformal design and can be used for communication, sensing, tracking, positioning, and many applications in different microwave frequency bands due to its wide-band frequency response. This model shows how to build a spiral geometry using parametric ... Read More
