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.
Due to abuse, such as internal or external short circuits or excessive heating, an individual battery cell may go into thermal runaway, during which the battery cell generates a significant amount of heat. If enough heat is transferred between adjacent cells during a thermal runaway ... Read More
An electrostatically actuated MEMS resonator is simulated in the time and frequency domains. The device is driven by an AC + DC bias voltage applied across a parallel plate capacitor. The dependence of the resonant frequency on DC bias is assessed, and frequency domain and transient ... Read More
This app demonstrates the following: Parametric geometry containing a geometry sequence with if-statements to produce different types of designs Options to set the mesh size A graphical user interface that includes different windows that can be shown or hidden Light Theme Water ... Read More
During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The ... Read More
In this model, the acoustics of the Small Hall in the Konzerthaus Berlin is simulated with ray tracing. A full study of the room is performed in 1/3-octave bands with 10 pairs of source-receiver positions. The room acoustic parameters are derived from the calculated impulse responses, ... Read More
This model demonstrates the simulation of the scattering of a plane wave of light by a gold nanosphere. The scattering is computed for the optical frequency range over which gold can be modeled as a material with negative complex-valued permittivity. The far-field pattern and losses are ... Read More
This example simulates the underground storage of CO2 in a part of the Johansen formation off the coast of Norway. The CO2 is injected using an injection well at a rate of 15 kg/s over a period of 25 years, after which the well is closed. The model is used to compute the spreading of CO2 ... Read More
This model demonstrates how to model phenomena defined in different dimensions in a fully coupled manner using COMSOL Multiphysics. Whereas in most cases the reaction rate expression is defined as a function of the concentrations of the reactants and products, in adsorption reactions ... Read More
Ultrasonic flowmeters determine the velocity of a fluid flowing through a pipe by sending an ultrasonic signal across the flow at a skew angle. When there is no flow, the transmitting time between the transmitter and the receiver is the same for the signals sent in the upstream and ... Read More
This model exemplifies the analysis of strong wind flow around a solar panel and the corresponding structural displacement due to the wind's load. The solar panel is located in an array of equally spaced identical panels, which allows for the assumption that the periodic flow conditions ... Read More
