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 demonstrates the path of relativistic protons within Earth's magnetic field. Due to the dipole nature of Earth's magnetic field, charged particles, such as electrons and protons, can get trapped in stable configurations within it for long periods of time. These ... Read More
A monopile foundation is a large-diameter structural element that can be used to support structures like offshore wind turbines. This application exemplifies how the cathodic protection of a monopile decreases over time as the sacrificial anodes dissolve. The model can be used to ... Read More
Microlaboratories for biochemical applications often require rapid mixing of different fluid streams. At the microscale, flow is usually highly ordered laminar flow, and the lack of turbulence makes diffusion the primary mechanism for mixing. While diffusional mixing of small ... Read More
Diffusion-induced stress in lithium-ion battery electrode materials can occur as a result of compositional inhomogeneities during lithium intercalation in the host material particles. These stresses are important since the electrode host material can undergo significant volume changes ... Read More
Portal Cranes are common when handling heavy loads. In this example, the Beam interface is used to compute the stresses in a portal crane designed for lifting 15 tons. Three load cases are considered: self weight, payload, and thermal expansion on a hot summer day. An internal hinge ... Read More
This tutorial studies the etching of silicon using an inductively coupled plasma reactor with an RF bias in a mixture of CF4/O2. The etching rate is computed along the wafer as a function of the RF bias voltage. 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
Removing halogen groups from hydrocarbons is an important reaction step in several chemical processes. One application is water purification. Other examples involve organic synthesis, where the removal of halogen groups serves as a starting point for carbon-carbon coupling reactions. ... Read More
This model includes a dielectric slab waveguide with a small lossy metallic object nearby. The object causes light to be scattered, absorbed, and both reflected and transmitted along the waveguide. Learn more in this accompanying blog post: Modeling a Scatterer Near an Optical Waveguide Read More
Stents are used in biomedical applications to support the inner wall of veins and arteries. Self-expanding stents made of shape memory alloys work differently from balloon-inflated stents, as these stents are crimped to the artery diameter at low temperature then released while the blood ...
