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 example demonstrates an app that utilizes the LiveLink™ interface for Solid Edge® to run simulations on CAD designs. Read More
This example exemplifies how to optimize the design of a capacitor through optimization. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Changing the Dimensions of a Model Using Shape Optimization". Read More
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 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
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
This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in PTC Pro/ENGINEER® by using the LiveLink™ interface. 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 compares the solution to the model equations of a tubular reactor using Danckwerts inlet and outlet conditions. A second almost identical model is defined with extra inlet and outlet sections where no reactions occur. The concentration at the beginning of the inlet section is ... Read More
This example demonstrates an app that utilizes the LiveLink™ interface for SOLIDWORKS® to run simulations on CAD designs. Read More
When estimating the parameters of a multiphysics model, both experimental noise and modeling uncertainties will contribute to corresponding uncertainties in the final parameters estimated. In this verification example, we demonstrate the new Variance functionality in the Parameter ... Read More
