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 application illustrates a modeling approach for deriving physically consistent simplified models in the Acoustics Module. The approach consists of converting complex sub-components to an impedance boundary condition and otherwise using simple acoustics throughout the COMSOL model. ... Read More
When radiation occurs across a very narrow gap this is often well-approximated as radiation between infinite parallel plates. This model considers three aluminum plates separated by narrow air gaps. The model compares the classical approach, based on the Surface-to-Surface Radiation ... Read More
This file shows how to create a surface of an irregular shape based on text, image, or elevation data. This approach is best suited for data where the height (or elevation) is a function of x- and y-coordinates. The data is of the Matterhorn, a European mountain located in the Alps. In ... Read More
This model demonstrates how to couple the Radiative Beam in Absorbing Media interface to the Radiation in Absorbing-Scattering Media interface. To learn more about this model, see our accompanying blog post “Modeling Absorption and Scattering of Collimated Light”. Read More
The model estimates the AC breakdown voltage between parallel electrodes in air by simulating charge transport dynamics. To keep computations efficient, it is implemented in one dimension, though it can be adapted for different gases and extended to higher-dimensional setups. The ... Read More
This model demonstrates how to use a space-time formulation to optimize a heating profile over time. Get an overview in the accompanying blog post Equation-Based Modeling with a Space-Time Discretization. Read More
This tutorial uses an equivalent circuit approach for modeling the performance of a lithium-ion battery, requiring no knowledge about the internal chemistry or structure of the battery. A 0D equivalent circuit battery model is defined based on a resistor connected in series with a ... Read More
This tutorial shows how to simulate coupled heat and moisture transport in a wall. The wall is modeled considering an air flow between interior and exterior varying with time. The 1D model is the third benchmark test defined in HAMSTAD-WP2 Modeling for the validation of numerical ... 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
In this extension of the model Optical Scattering off a Gold Nanosphere, the transmission spectra due to spherical nanoparticles of gold with varying radii dispersed in glass are computed and mapped onto the CIE 1931 and sRGB colorspaces. For a description of this model, see the ... Read More
