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.
In this first half of a two-part example, a 2D model of a trench-gate IGBT is built, which will be extended to 3D in the second half. In general, it is the most efficient to start with a 2D model to make sure everything works as expected, before extending it to 3D. The Caughey&ndash ... Read More
This application uses the shrinking core model to study the reduction of iron ore pellets. A 1D model of a packed bed containing iron ore pellets is modeled. The bed filling pellets initially consists of solid phase FeO. The pellets are reduced by CO, and the solid core shrinks leaving a ... Read More
This example minimizes the mass of a bracket that is synchronized from SOLIDWORKS® via the LiveLink™ interface. There are limits both for the lowest natural frequency, and for the maximum stress in a static load case. The size and position for a number of geometrical features ... Read More
Electrochemical codeposition is a common low-cost method for producing metal alloys. This tutorial model demonstrates electrodeposition of a nickel (Ni)–phosphorous (P) alloy. The model accounts for charge and mass transport of a multitude of species along with multiple electrode ... Read More
A square airbag made of a hyperelastic, compressible neo-Hookean material is inflated using pressurized air. Compressive stresses trigger wrinkling in some regions of the thin airbag. In this example, the wrinkling behavior is modeled using tension field theory, which gives a correct ... Read More
Compliant mechanisms are attractive due to their simplicity, owing to their lack of hinges. In this model we show how to design a set of compliant pliers using topology optimization. The resulting design is post-processed using shape optimization, where the maximum stress is constrained ... Read More
The Drift Diffusion interface solves a pair of reaction/advection/diffusion equations, one for the electron density and the other for the mean electron energy. This tutorial example computes the electron number density and mean electron energy in a drift tube. Electrons are released due ... Read More
This example solves the problem of finding the optimal thickness profile of a flywheel, so that the moment of inertia is maximized without increasing the mass or the maximum stress in the flywheel. Read More
This tutorial example illustrates the versatility of the Reaction Engineering interface. The hydrogen iodine reaction is modeled in a batch reactor with constant volume. Both isothermal and non-isothermal conditions are modeled. Read More
This model presents a method to analyze acoustic damping pads. These pads use a constrained layer of viscoelastic material to dissipate energy and thus reduce the energy radiated as noise. Damping pads are used in many different industries to reduce the noise generated by vibrating ... Read More
