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 parametrized model can be used to simulate the hopping hoop problem. A rolling ring with a point mass on the perimeter can, under certain conditions, jump up from the surface on which it is rolling. A more detailed description of this model can be found in the blog post "The ... Read More
The purpose of this app is to understand EIS, Nyquist, and Bode plots. The app lets you vary the bulk concentration, diffusion coefficient, exchange current density, double layer capacitance, and the maximum and minimum frequency. Electrochemical impedance spectroscopy (EIS) is a common ... Read More
This model is used to demonstrate the solution to a classic brainteaser in electromagnetics. A long loop of wire is connected to a source and a receiver, which are placed 1 meter apart. The objective of the model is to compute how long it takes for the receiver to sense when the source ... Read More
This example demonstrates how to apply inverse uncertainty quantification (IUQ) using the Uncertainty Quantification (UQ) Module in COMSOL Multiphysics to calibrate uncertain material properties of a resistor based on measurement data. When experimental data such as resistance values are ... Read More
This model simulates a beam of light being split into components of different frequencies when passing through a medium where the refractive index depends on frequency. COMSOL-wise, the model showcases two important technical aspects: A user-defined implementation of the frequency ... Read More
Thermally induced transformations in solids may be modeled by using an Arrhenius law to express the dependence on temperature of the transformation rate. This tutorial model shows how to use the Irreversible Transformation subfeature, available under the Solid feature of the Heat ... Read More
This example shows how to create a time-limited and hardware-locked application. It is associated with the section "Time-Limited and Hardware-Locked Applications" in the Application Programming Guide Read More
This example demonstrates the optimization of fiber orientation in a variable angle tow (VAT) laminate to maximize stiffness under prescribed loading and boundary conditions. The composite laminate consists of a single layer of carbon–PEEK composite with transversely isotropic material ... Read More
This model examines the behavior of a positive corona formed between concentric cylindrical conductors exposed to high applied voltages. The predicted current–voltage response closely matches the measurements. Rather than reproducing individual positive glow corona bursts, the setup ... Read More
This app generates random surfaces based on imported CAD models. Surfaces can be created using Gaussian or uniform random fields, analytical expressions, or combinations of random and deterministic fields. The app provides extensive customization options for controlling roughness, ... Read More
