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 model, a modal analysis is performed while parametrically sweeping the length of a waveguide from 0.5 um to 4 um to derive the dispersion curve for the anisotropic core. Both transverse and longitudinal anisotropy are considered in two different models. These models are ... Read More
This example treats the modeling of sub-surface flow where free convection in porous media is analyzed. The results are compared with published literature in the field. The model couples the momentum balance to an energy balance through an equation, dependent on temperature, being ... Read More
This slide deck introduces and demonstrates the modeling capabilities for crystallization and precipitation processes in COMSOL using the Size-Based Population Balance interface and Precipitation in Fluid Flow coupling feature released in 6.3. Read More
This model shows how to compute the anchor loss limited quality factor of a diamond disc resonator. The resonator is anchored to the substrate by a polysilicon post and power is transmitted to the substrate through the post. A perfectly matched layer is used to represent the essentially ...

This model example shows how to model nonlinear propagation of 1D finite-amplitude Acoustic waves in fluids using Acoustics Module of COMSOL Multiphysics. The model is based on the 2nd order Westervelt equation. The one dimensional nonlinear wave equation is solved in the time domain by ... Read More
This model demonstrates how to use the chatbot functionality in COMSOL Multiphysics® to add annotations to a model of a pacemaker electrode. To learn more about this model, see our accompanying blog post “Using the Chatbot Window in COMSOL Multiphysics®”. 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
Oscillating chemical reactions were long thought to simply not exist in homogeneous solution, and even the poster child, the Belousov–Zhabotinsky reaction, met such an initial skepticism, that even though it was discovered in 1951, it took almost 20 years for it to gain widespread fame. ...

For a description of this model, see our accompanying blog post "Can COMSOL Multiphysics® Solve the Hydrogen Atom?". Read More
In this set of eight tutorial models and associated documentation, you can investigate the resistive, capacitive, inductive, and thermal properties of a standard three-core lead-sheathed XLPE HVAC submarine cable with twisted magnetic armor (500 mm2, 220 kV). The series includes a 2D, 2D ... Read More
