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 model demonstrate how to simulate ray tracing in a pinhole camera viewing a solar eclipse. To keep the model dimensions in check, the Sun and Moon are approximated using planar discs with the appropriate angular size (~0.5 degree) relative to the pinhole. In this example, the ... Read More
This local demo database for the Model Manager contains an imported copy of the Application Library models in COMSOL Multiphysics® version 6.0 and above. You can add this database from COMSOL Multiphysics® by selecting Download Demo Database for Model Manager from the ... Read More
This example demonstrates an app that utilizes the LiveLink™ interface for Solid Edge® to run simulations on CAD designs. Read More
Fractals exhibit self-similarity at different scales and are often found in nature. Fractal noise is a technique used to emulate organic-looking textures, such as to achieve realistic visualizations of various materials in COMSOL Multiphysics®. These models demonstrate how to ... Read More
This example uses the Granular Flow interface to model the fixed funnel method for calculating the angle of repose, where a funnel is kept at a fixed height. The funnel is first filled with grains which are subsequently released and collected as a heap. The resultant heap is then ... Read More
This example exemplifies how to model the impedance of a waveguide of varying cross sectional area. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Computing the Impedance of a Corrugated Waveguide". 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
In this model of a single-beam optical trap, SiO2 nanospheres in streaming water pass by or get captured depending on where they are released from. The electromagnetic force on the particles is calculated in the Electromagnetic Waves, Frequency Domain interface, with a Gaussian ... Read More
Polymerase chain reaction (PCR) is one of the most effective methods in molecular biology, medical diagnostics, and biochemical engineering in amplifying a specific sequence of DNA. There has been a great interest in developing portable PCR-based lab-on-a-chip systems for point-of-care ... Read More
This model describes a pencil beam scanning (PBS) magnet system for use in medical proton therapy. Simulations of the magnetic flux density and particle tracing are performed. Such models are useful for the design of PBS systems, particular with the advent of MR-integrated proton ... Read More
