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 how to optimize the charging profile of a battery using gradient based optimization. The optimization solver minimizes the time required for charging the battery from 0% to 90% state of charge, while at the same time constraining the amount lithium inventory lost ... Read More
Tutorial example of a Erlang SEIR model for the epidemic of COVID-19. The model is validated against data from China, Sweden, and the US. Parametric estimation is done using the reported deaths over time. The tutorial investigates the impact of social distancing on the progress of the ... Read More
This example illustrates the modeling of a tensegrity table. The table is made of two rigid bodies connected through a central wire and four outer wires. Two cases are analyzed. In the first case, the top of the table is loaded with vertically downward acting load of varying magnitude. ... Read More
This app simulates sedimentation of particles or agglomerations of particles in a solution. The distribution of particles or agglomerations of particles is taken into account. Read More
In this model, the transmitter (microstrip patch) and receiver (Yagi–Uda) antennas are modeled simultaneously in the FEM domain and are coupled with FEM–BEM coupling. The results are compared with the analytical Friis transmission formula. In detail, the emw and emw2 interfaces find out ... Read More
Formally known as size separation in vibrated granular materials, the Brazil nut effect (BNE) (and sometimes the Muesli effect) is a phenomenon that causes large grains to separate from small ones and rise to the top of a granular bed under vibrations. This phenomenon can be studied ... Read More
This example shows how to model Lithium diffusion in a silicon electrode that swells. The model shows how swelling-induced plastic deformation can increase the maximum state of charge (SOC). Read More
You can use the Moving Mesh or the Deformed Geometry interface to implement wrapping of a CAD part around one axis. This model demonstrates both how to implement this wrapping, as well as how to subsequently mesh the surrounding volume around the deformed part. A more detailed ... Read More
This document explains how to install and run COMSOL Multiphysics® and COMSOL Server™ with Microsoft® Azure. This requires that you have first acquired a Floating Network License (FNL) or COMSOL Server License (CSL) from COMSOL. The license manager software can run ... Read More
This tutorial model demonstrates the use of the multiphysics coupling feature Thermal Connection, Layered Shell, Edges. In this model, three layered shells are connected to heat domains by edges at difference locations related to the heat domains. The results obtained with the Heat ... Read More
