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.
In this model, we use the Bioheat Transfer interface to solve the Pennes bioheat transfer equation. The problem is in 1D and formulated to be dimensionless. The results are compared against analytical solutions derived in a journal paper (Ref. 1). A mesh convergence study shows that the ... Read More
This example demonstrates an app that utilizes the LiveLink™ interface for Solid Edge® to run simulations on CAD designs. Read More
In food industries, microwave heating is gaining attention over a conventional heating treatment because of several advantages such as precise process control, speed of heating, fast turn-on and turn-off time, etc. In this model, a high directional Yagi-Uda antenna is used to heat up ... Read More
Finding acoustic eigenmodes in problems solved with linearized convected acoustic interfaces can be a challenging task. The solution will most often return several non-acoustic vorticity and entropy modes. These are highly damped waves that do not propagate at the speed of sound but with ... Read More
Thermally induced transformations in solids may be modeled by using an Arrhenius law to express the dependence on temperature of the transformation rate. This tutorial model shows how to use the Irreversible Transformation subfeature, available under the Solid feature of the Heat ... Read More
This example shows how to image the interior permittivity of a box by applying a potential difference on the boundaries of the box. The result is a surface charge density that depends on the permittivity of the medium inside the box. Read about this tutorial model in our blog post "The ... Read More
Example for a geometry sequence to deduce a shell model from an imported solid CAD file. The model demonstrates how to generate parameters from dimensions of a geometry and how to convert a solid CAD geometry into a shell representation using midsurface and extract Read More
Find the optimal cross section areas of trusses in a structure given a prescribed set of limitations and a clear objective. The structure is made up of trusses which are elements that can only sustain axial forces. 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
