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 exemplifies the basic principles of crevice corrosion and how a time-dependent study can be used to simulate the electrode deformation. The model is in 2D and the polarization data for the corrosion reaction is taken from a paper by Absulsalam and others. The model and the ... Read More
The Cathodic Protection Designer application is an example of how an application can be used to simplify the simulation process by featuring a way to import a generic CAD file with certain requirements. Using this app, the user can select each part of the geometry and set boundary ... Read More
Surface plasmon polariton (SPP) as well as other types of surface electromagnetic waves is of great interest due to unique physical properties and application potentials. The models here demonstrate how to simulate SPP propagation and its frequency-momentum dispersion relation. The ... Read More
This benchmark demonstrates how to use the Beam interface in the Structural Mechanics Module. It calculates the deformation, section forces, and stresses in a cantilever beam as well as a number of eigenfrequencies. It also illustrates how to use the Beam Cross Section interface to ... Read More
The Magnus effect explains the curl that soccer players can give the ball, resulting in the enjoyable goals that we can see in every FIFA World Cup™. This model looks at the Magnus effect in the laminar and turbulent flow regimes for transient and stationary flows. It also discusses ... Read More
This tutorial model shows the setup of a 2D axisymmetric stress analysis, through contact, of a 3D threaded pipe fitting. The example involves synchronizing the 3D PTC Creo Parametric™ geometry and selections, which specify the faces in contact, with the 2D geometry in COMSOL ... Read More
This is the model of the acoustics in a particulate-filter-like system. Real systems, like diesel particulate filters (DPFs), are designed to remove/filter soot (diesel particles) from the exhaust of diesel engine vehicles. The porous medium in such systems are typically structured with ... Read More
Sound is generated by a point source located in the wall of this test bench car interior. The sound pressure level response at a point of measurement is investigated for a range of frequencies and four different mesh resolutions. The model is first solved with the default direct solvers. ... Read More
The noise emitted from an electrical machine can have many sources. In this example, acoustic noise from vibrations created by magnetic force variation is studied. Such noise is often audible at twice the excitation frequency but can also occur at higher frequencies or harmonics of the ... Read More
This tutorial shows how to solve the full time-dependent wave equation in dispersive media such as plasmas and semiconductors. The 2D TM in-plane wave model solves for the vector potential from the wave equation and for an auxiliary electric polarization density from an ordinary ... Read More
