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.
Instability of a Space Arc Frame
This model illustrates the instability of a space arc frame under concentrated vertical loading. The Beam interface is utilized. Two different approaches are used: A full incremental nonlinear analysis, where a small lateral load is applied to break the symmetry of the structure A ... Read More
Electrical Heating in a Busbar Assembly
Model of electrical heating of a busbar that demonstrates how to use LiveLink™ for SolidWorks® together with LiveLink™ for MATLAB®. The MPH-file required to run the model can be found in Electrical Heating in a Busbar Assembly Read More
Annular Ultraviolet Reactor, Optically Transparent Water
Fluence rate is a key parameter for ultraviolet (UV) water purifier. It describes the amount of radiation that pathogens absorb and is then directly related to the disinfection level of the purifier. The aim of this example is to demonstrate the fluence rate calculation with the ... Read More
1D Plane Slider Bearing
This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic slider bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. Read More
Fast Modeling of a Transmission Line Wilkinson Power Divider
Some conventional three-port power dividers are resistive power dividers and T-junction power dividers. Such dividers are either lossy or not matched to the system reference impedance at all ports. In addition, isolation between two coupled ports is not guaranteed. The Wilkinson power ... Read More
1D Step Bearing
This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic step bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. Read More
Geometric Parameter Optimization of a Tuning Fork
This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Creo Parametric via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz. Read More
Electrochromic Device
Electrochromic devices (ECDs) may be employed in ”smart” windows, for instance in buildings or motor cycle visors, where the transparency of the device can be controlled by applying a voltage. ECDs make use of the fact that the absorbance of visual light for a chemical species in a ... Read More
Keck Telescope
The Keck Telescope is a 10 meter diameter telescope with a Ritchey-Chretien optical design. It is noted for being one of the first large optical telescopes to utilize a lightweight segmented primary mirror. This tutorial demonstrates how to use built-in polygonal mirrors from the COMSOL ...
