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 shows how to build and solve a radiative heat transfer problem using the Heat Transfer interface. In particular, this 2D model illustrates the use of the surface-to-surface radiation feature. In this model, three surfaces form a cavity. Heat flux is set at two outer ... Read More
Follow this tutorial series to learn about how to work with imported surface meshes. The instructions detail how to import STL files of three vertebrae and two intervertebral discs as well as how to repair holes, misaligned mesh vertices, and intersecting elements. It further ... Read More
The models simulate the working mechanism of traveling wave thermoacoustic engines. Similary to the standing wave engines, the traveling wave engines make use of the coupling between the fluid motion and the temperature change experienced by the fluid to generate acoustic energy. ... Read More
This app demonstrates the following: Multiple components (1D and 3D) in a single app Using the same choice list in the app as in the model using Data Access functionality Output numerical results for a specific time step using a combo box The app combines the Ray Optics Module and ... Read More
A slope stability analysis is performed and the Factor of Safety of the dam embankment is calculated by using the Shear Strength Reduction Technique. The pore pressure in the soil is computed based on Darcy’s law, and the Mohr–Coulomb constitutive model is used to describe the ... Read More
This model simulates an electrodeless lamp with argon/mercury chemistry. The low excitation threshold for mercury atoms means that even though the mercury is present in small concentrations, its behavior dominates. There is strong UV emission from the plasma at 185 nm and 253 nm. The UV ... Read More
Galvanic corrosion between two different phases (alpha and beta phases) in a metallic (magnesium) alloy is simulated for a representative cross-sectional microstructure configuration. A key feature in the model formulation is the implementation of both anodic and cathodic regions at ... Read More
A Fabry-Perot resonator is one of the fundamental optical devices and has a broad range of applications. A few examples are that it can be used to measure length, frequency/wavelength or to filter specific spatial modes. This model uses the Beam Envelopes Interface in the bidirectional ... Read More
Digital Rock technology utilizes high-resolution imaging techniques, such as SEM and X-ray CT, to characterize the pore structures of rock cores. This approach enables pore-scale modeling of reservoir rocks, offering valuable insights into pore morphology, connectivity, and fluid ... Read More
This example shows an approximate approach to model a dot-in-well solar cell as described by Asahi et al. in the reference paper. The quantum wells and the layers of quantum dots are each treated as lumped energy levels in the band gap. The authors specify transitions between the dot ... Read More
