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.
One of the most common reactors in the chemical industry, for use in heterogeneous catalytic processes, is the packed bed reactor. This type of reactor is used both in synthesis as well as in effluent treatment and catalytic combustion. The reactor consists in essence of a container ... Read More
This tutorial model solves for an inductively coupled plasma reactor with RF bias (also known as ICP/CCP reactors) in a mixture of argon/chlorine. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. Read More
During an internal short circuit of a battery, the two electrode materials are internally and electronically interconnected, giving rise to high local current densities. Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a ... Read More
When a linear guide is loaded above the manufacturer's specification limit, one concern is whether the contact loads will introduce fatigue spalling. In this system analysis, the entire guide has been analyzed and the mostly damaging contact load has been identified to occur on a rail ... Read More
This example shows how to model a load which varies in space and time. A series of load pulses travel along a beam which is supported at equal distances. For some combinations of the traveling speed of the load pulses and the spacing between them, it is possible to excite resonances in ... Read More
This tutorial models the cathodic protection of an oil rig structure during a time period of 15 years. As a result of the consumption of the sacrificial anodes, the protective capabilities system are reduced over time. The anode shape change in the model is defined by using the Level ... Read More
In friction stir welding, a rotating tool moves along the weld joint and melts the aluminum through the generation of friction heat. The tool’s rotation stirs the melted aluminum such that the two plates are joined. In this model, two aluminum plates are joined by generating friction ... Read More
This example models time-dependent copper deposition on a resistive wafer in a cupplater reactor. As the deposited layer builds up, the resistive losses of the deposited layer decreases. The benefit of using a current thief for a more uniform deposit is demonstrated. Read More
This is a conceptual model illustrating how to couple fluid-structure interaction, heat transfer, and thermal expansion. A bimetallic strip in an air channel is heated so that it bends. After some time, an airflow with an inlet temperature which varies in time is introduced. As a ... Read More
This model shows how to use the Free Shape Boundary feature to increase the stiffness of a wrench without increasing its mass. Read More
