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.
Magnetic prospecting is a geological exploration method that is applicable to certain types of iron ore deposits, in particular those made up of magnetite and hematite. The method consists of measuring the magnetic anomalies (changes in the earth's magnetic field) due to the presence of ... Read More
Sodium-ion batteries (SIB) are commonly presented as an alternative to lithium-ion batteries (LIB). The SIB chemistry uses Na+ instead of Li+ for electrolyte charge transport and as redox species in the electrode reactions, with the advantage of Na+ being more abundant and with a ... Read More
This tutorial shows how to clean an imported CAD geometry using Geometry Cleanup. This helps to improve the mesh and reduce the total number of elements. Read More
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
A model of a thermal microactuator requires the coupled simulation of electric current conduction with heat generation, heat conduction, and structural stresses and strains due to thermal expansion. The purpose of this model is to demonstrate how to access the cluster computing ... Read More
Lithium iron phosphate (LFP) is a common positive electrode material in lithium-ion batteries. Specific for the LFP electrode material is that its equilibrium (open circuit) potential, when defined as a function of the lithiation state, features a large flat plateau with a more or less ...

The pyrolysis of a centimeter-sized wood particle presents a fully coupled multiphysics problem with mass transfer, fluid flow, and heat transfer. This example model consists of two parts. The first part demonstrates how to set up a model describing the pyrolysis of a porous, ... Read More
A quadrupole mass filter (QMF) is a key component of a modern mass spectrometer. A QMF uses direct current (DC) and alternating current (AC) electric fields to analyze positive or negative ions by mass to charge ratio. A QMF consists of 4 parallel rods spaced equidistantly, the ratio of ... Read More
This model shows how to combine an electric circuit simulation with a finite element simulation. The finite element model is an inductor with a nonlinear magnetic core and 1000 turns, where the number of turns is modeled using a distributed current technique. The circuit is imported ... Read More
This example illustrates multiphase flow modeling in an airlift loop reactor. The reactor is filled with water and air bubbles are injected at the bottom through two frits. Due to buoyancy, the bubbles rise, inducing a circulating motion of the liquid. The model specifically investigates ... Read More
