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.
Cupric ions show a strong affinity to ammonia in aqueous solutions, forming strongly colored deep blue complexes. The relative amounts of the different ammine ligand complexes, with varying coordination numbers, are governed by the stability constants of the equilibria forming the ... Read More
This model presents a method to analyze acoustic damping pads. These pads use a constrained layer of viscoelastic material to dissipate energy and thus reduce the energy radiated as noise. Damping pads are used in many different industries to reduce the noise generated by vibrating ... Read More
Model of the sound radiation from a circular duct with uniform flow. The convected acoustic problem is described using the linearized potential flow equations, solved in the frequency domain. The acoustic inlet is treated including higher order modes using the Port boundary condition and ... Read More
Underground train grids span large areas under London, Paris, New York, and other cities. The building regulations require strict noise standards, and failure to comply could result in significant losses in the market prices of developments. Therefore, train-induced noise has to be ... Read More
Lithium iron phosphate (LFP) is a common positive electrode material in lithium-ion batteries. Specific for the LFP electrode material is that its equilibrium (open circuit) potential, when defined as a function of the lithiation state, features a large flat plateau with a more or less ...

This tutorial model demonstrates the use of the Moisture Flow coupling node to account for the Stefan flow in moist air, over an evaporation surface. The effects on the velocity field and vapor concentration are presented with different ambient temperature conditions. Read More
Example for a geometry sequence to deduce a shell model from an imported solid CAD file. The model demonstrates how to generate parameters from dimensions of a geometry and how to convert a solid CAD geometry into a shell representation using midsurface and extract Read More
This model demonstrates how to vary the inlet temperature in a superheated steam drying process so as to minimize the time, while constraining both the energy consumption and the final moisture content. Read More
This tutorial demonstrates how to model a gyroscope based on the birdbath resonator gyroscope (BRG) design. The BRG is a type of Coriolis vibratory gyroscope (CVG) invented at the University of Michigan as a navigation-grade gyroscope in the mm-scale. This tutorial shows how the ... Read More
This app demonstrates the following: Using the knob form object Updating the geometry by rotating a knob Provides info if the results are above or below certain critical values Many trucks are equipped with cranes for handling loads and such cranes have a number of hydraulic ... Read More
