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 full-scale, time-dependent model of an offshore oil platform jacket involves modeling coating breakdown and estimating sacrificial anode life and the buildup of calcareous deposits on steel surfaces. The tutorial model aims to answer some of the common questions surrounding ... Read More
This tutorial demonstrates how to use the temperature and relative humidity computed from a heat and moisture transport simulation of an insulated roof as inputs for a mold prediction model. The VTT model for mold growth and decline prediction calculates a mold index M by solving an ... Read More
The COMSOL® software includes capabilities for 3D plasma modeling. In this example, a square coil is placed on top of a dielectric window and is electrically excited at 13.56 MHz. A plasma is formed in the chamber beneath the dielectric window, which contains argon gas at low ... Read More
The Free Molecular Flow interface, available in the Molecular Flow Module, is an efficient tool for modeling extremely rarefied gases when the gas molecules move much faster than any geometric entities in the domain. For turbomolecular pumps, in which the blades move at speeds comparable ... Read More
Continuous mixing is used in process equipment to mix components in a single pass. Compared to batch mixing, this operation has the advantage that the tank filling and emptying steps are eliminated, implying that the process can be run without interruptions. A disadvantage of continuous ... Read More
This model verifies that the onset of streamer formation between two spheres separated by atmospheric pressure dry air at a distance of 2cm occurs at 51.8kV. The electrical breakdown is detected by integrating Townsend coefficients along the electric field lines between the two spheres. ... Read More
A monopile foundation is a large-diameter structural element that can be used to support structures like offshore wind turbines. This application exemplifies how the cathodic protection of a monopile decreases over time as the sacrificial anodes dissolve. The model can be used to ... Read More
The standard biventricular cardiac model is used to show how to set up fiber directions in a complex geometry. The fibers are then used to model the large deformation of the myocardium with the Holzapfel-Gasser-Ogden anisotropic material model. The Aliev-Panfilov equations are included ... Read More
This is a full vibro-electroacoustic simulation of a balanced armature transducer (BAT or also known as a receiver in some industries) which is a high-performance miniature loudspeaker often used in hearing aids and other in-ear audio products such as earbuds. The model is set up and ... Read More
This model simulates a temperature profile in a number of cells and cooling fins in a liquid-cooled battery pack. The model solves in 3D and for an operational point during a load cycle. A full 1D electrochemical model for the lithium battery calculates the average heat source. Read More
