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.
Tesla microvalves exploit the non-linear nature of inertial flow to create anisotropic flow resistance. They can be used as robust valves owing to their passive working mechanism, but for many applications the diodicity is too low. Two-dimensional simulations and optimization over ... Read More
This tutorial model demonstrates the use of the features for heat transfer in layered shells, to account for the curvature of the layers when applying heat fluxes and heat sources. The results obtained with the Heat Transfer in Shells interface applied to a boundary (with extra ... Read More
These examples demonstrate how to use a job sequence to perform a programmatic sequence of operations, including solving; saving the model to file; and generating and exporting plot groups, results, and images. In the blog post associated with these files, "How to Use Job Sequences to ... Read More
The miniaturization of electronics devices requires batteries with higher energy density and power. To increase the contact area between the electrodes and the solid electrolyte, 3D configurations such as the trench geometry are used. This example demonstrates how to model a solid-state ...

Two approaches are demonstrated to introduce a goal-seeking Global Equation into a COMSOL Multiphysics® model. This Global Equation acts to adjust a single input of the model such that any single scalar output of the model takes on a desired target value, or goal. Learn more in ... Read More
The model shows how to estimate the Young's modulus and Poisson ratio based on a tensile test. The test measures the tensile force and the radial displacement. Typical numerical values of these quantities differ with around 10 orders of magnitude. Using a maximum likelihood strategy ... Read More
This model demonstrates two ways of modeling waveguides that support multiple modes. A PML can be used to absorb any modes, or Ports can be explicitly added for each possible mode. Learn more in this accompanying blog post: Modeling Waveguides that Support Multiple Modes Read More
The sound distribution from a TV in a two-room apartment is computed. The simulation demonstrates the use of the Acoustic Diffusion Equation interface to get a quick and simple estimate of the local sound pressure level. For increased accuracy, an analytical expression for the direct ... Read More
This model uses the Ray Acoustics interface to extract statistical information about a room. Two examples of rooms are analyzed: The staircase from the One-Family House Acoustics tutorial model A long corridor The models compute the mean free path as well as the reflection frequency ... Read More
This example of a plasmonic waveguide filter shows that the waveguide rejects the electromagnetic radiation of the wavelength between 1.4 um and 1.6 um, but allows the rest of the wavelength. The silver material can be modeled using the Drude-Lorentz approximation, with ε∞ = 3.7, ωp = 13 ... Read More
