Permanent Magnet
As an example of a magnetostatic problem, consider how to model a horseshoe-shaped permanent magnet. One way is to treat the entire magnet as a ferromagnetic material, where the two end sections are defined as being pre-magnetized in different and opposite directions. En savoir plus
Heat Transfer by Free Convection
This example describes an array of heating tubes submerged in a vessel with fluid flow entering at the bottom. This is a multiphysics model because it involves fluid dynamics coupled with heat transfer. The pressure and the velocity field are the solution of the Navier-Stokes equations, ... En savoir plus
Heating Circuit
Small heating circuits find use in many applications. For example, in manufacturing processes, they heat up reactive fluids. The device in this tutorial example consists of an electrically resistive layer deposited on a glass plate. The layer results in Joule heating when a voltage is ... En savoir plus
Magnetic Field of a Helmholtz Coil
A Helmholtz coil is a parallel pair of identical circular coils spaced one radius apart and wound so that the current flows through both coils in the same direction. This winding results in a uniform magnetic field between the coils with the primary component parallel to the axes of the ... En savoir plus
Alkaline Electrolyzer
Alkaline water electrolysis is a well-established industrial process for producing hydrogen gas. In the cell, hydrogen gas is formed at the cathode whereas oxygen gas is formed at the anode. The electrolyte is an aqueous liquid, and when the evolved gases form bubbles, the effective ... En savoir plus
Fluid–Structure Interaction
This model demonstrates how to set up a fluid-structure interaction problem in COMSOL Multiphysics. It illustrates how fluid flow can deform solid structures and how to solve for the flow in a continuously deforming geometry. The Fluid-Structure Interaction (FSI) multiphysics interface ...

Dam Breaking on a Column, Level Set
This transient model uses the Two-Phase Flow, Level Set, Laminar Flow interface to model the impact of a water wave on a column. A body of water with a height of 0.3 meters is initially contained behind a gate. At the start of the simulation, the gate is suddenly released and the body of ... En savoir plus
Pore-Scale Flow
This non-conventional model of porous media flow utilizes creeping (Stokes) flow in the interstices of a porous media. The model comes from the pore-scale flow experiments conducted by Arturo Keller, Maria Auset, and Sanya Sirivithayapakorn of the University of California, Santa Barbara. ... En savoir plus
Stresses and Strains in a Wrench
This tutorial demonstrates how to set up a simple static structural analysis. The analysis is exemplified on a combination wrench during the application of torque on a bolt. Despite its simplicity, and the fact that very few engineers would run a structural analysis before trying to turn ... En savoir plus
Thermal Modeling of a Cylindrical Lithium-Ion Battery in 3D
This example simulates the heat profile in an air-cooled cylindrical battery in 3d. The battery is placed in a matrix in a battery pack. The thermal model is coupled to a 1d-battery model that is used to generate a heat source in the active battery material. The model requires the ... En savoir plus
