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 the usage of the Scattered Field formulation to compute the scattering of light off of a single scatterer on top of a dielectric half-space. It uses the analytic Fresnel equations to design the background field. For a detailed introduction to this model, see ... Read More
This model showcases the broadband optimization for the Microstructured antireflective coatings that are modeled in the model (#99011). Following are the parameters that are optimized: Rectangular microstructure: Height and width of the rectangular microstructure. Pyramidal ... Read More
This tutorial illustrates the use of the connecting features in the Heat Transfer in Solids and Heat Transfer in Shells interfaces, to couple them to a Lumped Thermal System interface. The results obtained with the solid and shell models are compared. Read More
This example exemplifies how to model thermal phase change that is subject to hysteresis. A more detailed description of the phenomenon, and the modeling process, can be seen in the blog post "Thermal Modeling of Phase-Change Materials with Hysteresis" as well as: "How to Use State ... Read More
One of the possible formats when working with scanned data is images for the slices of an MRI or CT scan. This is an example with images from the cross sections of the different levels of a human head. In short, the procedure includes creating curve objects of each of the images using ... Read More
When designing oxygen masks for delivering respiratory support to patients via BiPAP and CPAP, multiphysics modeling helps visualize the flow pattern inside the mask for a given design. From there, it is possible to estimate oxygen consumption, carbon dioxide accumulation, and ... Read More
This simple tutorial model shows how to set up a parametric sweep over a number of frequency bands (octaves or 1/3 octaves) and remesh once per band. A frequency sweep is performed within each band, which now has an adequate mesh resolution. This approach saves some computational effort ... Read More
The purpose of this model is to introduce the Semitransparent Surface Feature from the Radiation in Participating Media Interface. It is a variation of the Radiative Cooling of a Glass Plate model with the DOM method. In this version a semitransparent surface is defined on external ... Read More
Example of membrane dialysis with a two-layered membrane. A second Reaction Engineering component models a tank connected to the inlet and outlets of the dialysate channel. Read More
In a polymer electrolyte membrane water electrolyzer cell, hydrogen and oxygen gas is produced by electrolysis. The hydrogen and oxygen compartments are separated by a polymer membrane, that also acts as electrolyte. This introductory tutorial computes the ohmic and activation losses in ... Read More
