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 model analyzes the scattering of a plane propagating modulated Gaussian pulse off a submarine hull. The scattered field and the spatial response are also determined. The model uses the Pressure Acoustics, Time Explicit interface to model this large acoustic model in the time domain. ... Read More
This 2D example of a vanadium flow battery demonstrates how to couple a secondary current distribution model for an ion-exchange membrane to tertiary current distribution models for two different free electrolyte compartments of a flow battery. The Ion-Exchange Membrane boundary node ... Read More
This example models the flow and mass transport in the channels and the gas diffusion layer (GDL) of a polymer electrolyte fuel cell. The cathode electrode reaction is modeled as a boundary condition, where the local current density depends on the overpotential and the local oxygen ... Read More
This 2D stationary model computes heat and moisture transport in a wall composed of different hygroscopic materials. A comparison with the Glaser method is given for the temperature and relative humidity solutions. The effect of the use of a vapor barrier is also investigated. Read More
This model describes the three heat transfer modes: conduction, convection, and radiation, combined with nonisothermal flow in a realistic geometry representing a light bulb and the surrounding air. The LED chips dissipate heat. The model computes the equilibrium temperature induced by ... Read More
This tutorial shows how to use the Optimization interface to perform electrode kinetics parameter estimations based on polarization data. A zero-dimensional electrode polarization model is defined that separates kinetics expressions for the metal dissolution and the oxygen reduction ... Read More
The use of Aluminum (Al) isolator is a commonly employed mitigation strategy for galvanic corrosion between magnesium alloy (Mg) and mild steel (MS). The present model demonstrates the effect of Al isolator thickness on galvanic corrosion severity using a parametric study. The electrode ... Read More
This tutorial model explains how to extract lumped matrices by means of the Stationary Source Sweep study. The capacitance matrix of a five-terminal system is used to infer the position of a metallic object similar to real-world capacitive position sensors. The example illustrates the ... Read More
Piezoelectric devices are widely used as sources to generate sound waves or receivers to detect acoustic signals. In applications such as ultrasound imaging and nondestructive testing, the same transducer can be used as a transmitter to send a source signal and receiver to detect ... Read More
Anechoic coatings are used on submarines to reduce sonar reflections. This model calculates the reflection, absorption, and transmission properties of an anechoic coating on a steel plate. The calculated results from this sub-model can be used in larger system scale models, for example, ... Read More
