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 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 model illustrates how to compute the torque of a three-phase squirrel-cage induction motor at various speeds. In the example the torque is computed by averaging the results from simulations performed on 2D cross sections at several locations along the induction motor. The 3D ... Read More
The model has its emphasis on heat transport in a very small heat exchanger that is commonly used in the field of microelectromechanical systems (MEMS). In this case, it might be a reactive processes that needs heating. The heat exchanger itself is constructed by stacking several ... Read More
Micropumps are key components of microfluidic systems with applications ranging from biological fluid handling to microelectronic cooling. This model simulates the mechanism of a valveless micropump, that is designed to be effective at low Reynolds numbers, overcoming hydrodynamic ... Read More
Pitting corrosion is localized corrosion by which local cavities, pits, are formed on a seemingly initially smooth metal surface. A pit may be initiated due to small surface defects, such as inhomogeneities in composition or shape, or from mechanical abuse. How and if the pit grows ... Read More
This model is intended as a first introduction to simulations of fluid flow and conjugate heat transfer. It shows you how to: Draw an air box around a device in order to model convective cooling in this box, set a total heat flux on a boundary using automatic area computation, and ... Read More
A trimmer capacitor has a variable capacitance. One way of obtaining this is to use parallel facing electrodes with a variable overlap area. In this example, the capacitance can be changed by turning one electrode using a screwdriver. Typically a linear angular response is desired. ... Read More
This tutorial demonstrates the operation of a gyroscope based on design provided by Dr. James Ransley at Veryst Engineering, LLC. The model uses the Electromechanics coupling with the mixed finite element formulation in the Electrostatics interface. Read More
When a droplet is placed on a substrate on which surface acoustic waves (SAWs) are traveling, the energy of the SAWs is transferred into the droplet to form an acoustic field. The transferred energy is attenuated and generates a streaming flow. This type of streaming enables contactless ... Read More
Squeeze film dampers are components that provide additional damping to rotating machines. To simplify the modeling of a rotor assembly, squeeze film dampers are modeled in terms of their damping coefficients which are a functions of the journal location in the damper. This model computes ... Read More
