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.
Transient Gaussian Explosion
An ellipse with sound-hard walls has the interesting property that an acoustic signal emanating from one of the foci refocuses at the other focal point b/c seconds later, where b (in meters) is the major axis length and c (m/s) is the speed of sound. This model involves a Gaussian ... Read More
Large Eddy Simulation of a 3D Hill Geometry
The present example simulates the turbulent flow over a 3D hill geometry using the Large Eddy Simulation (LES) interface with synthetic turbulence at the inlet boundary. Read More
Nonisothermal Reacting Flow in a Methane Steam Reformer
This model uses the Reacting Flow multiphysics interface to simulate a methane steam reformer. The model accounts for the interactions between the chemical reactions, the transport of species, the fluid flow, and the heat transfer in a porous medium. Read More
Nonisothermal Plug-Flow Reactor
This example considers the thermal cracking of acetone, which is a key step in the production of acetic anhydride. The gas phase reaction takes place under nonisothermal conditions in a plug-flow reactor. As the cracking chemistry is endothermic, control over the temperature in the ... Read More
Magnetic Prospecting of Iron Ore Deposits
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
1D Isothermal Nickel–Metal Hydride Battery
This model simulates the discharge of a Nickel-Metal Hydride (NiMH) battery using the Battery with Binary Electrolyte interface. The geometry is in one dimension and the model is isothermal. The model serves as an introduction to NiMH modeling, and can be further extended to include ... Read More
Greenhouse Effect
This model illustrates the greenhouse effect in a box covered by a plate and exposed to sun radiation over a day. The temperature variation is monitored in two cases: with a plate made of glass, transparent in the solar spectral band and opaque for the ambient solar band with a fully ... Read More
Equivalent Properties of Periodic Microstructures
This app demonstrates the following: Visualization of a periodic structure from a unit cell Resetting some or all input parameters Export the resulting material properties as an MPH-file or an XML-file that can be imported to a COMSOL Multiphysics session Periodic microstructures are ... Read More
Analyzing Electric Motor and Generator Designs
This is a primer model of a permanent magnet machine. It is a generic model that can be modified to simulate a motor or generator. It demonstrates different capabilities of COMSOL Multiphysics® to examine aspects of machine design, such as air gap magnetomotive force (MMF), ... Read More
Tensile Test with Strain Rate Dependent Plasticity
In this example, a tensile test is simulated at four different strain rates. The Johnson–Cook hardening law is used to model the strain rate dependency of the plastic hardening. The temperature distribution and thermal expansion caused by the heating generated by the plastic ... Read More
