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.
Importing Curve Data and Lofting a Solid
One of the possible formats when working with scanned data is text files with coordinate data created from images for the slices of an MRI or CT scan. This is an example with 3D coordinate files from the cross sections of the different levels of a human head. Each coordinate file ... Read More
Atmospheric Corrosion
This model simulates atmospheric galvanic corrosion of an aluminum alloy in contact with steel. The electrolyte film thickness depends on the relative humidity of the surrounding air and the salt load density of NaCl crystals on the metal surface. Empirical expressions for the oxygen ... Read More
Shape Optimization of a Tesla Microvalve
The topology optimized Tesla microvalve is used as an inspiration for an initial geometry. Second order Bernstein polynomials are used to perturb the shape of the geometry. The resulting design is remeshed in the deformed configuration and the performance is investigated for a range of ... Read More
Angle Crack Embedded in a Plate
This example reproduces a NAFEMS benchmark in which a plate with an angle crack is subjected to tensile loading. The J-integral is calculated and the stress intensity factors for Mode I and Mode II are compared to the benchmark results for several crack angles. Read More
Modeling of a Mobile Device Antenna
Electrical components in wireless communication systems are designed to be small and light for portability and productivity while maintaining decent performance and efficiency. Antennas are essential components in mobile devices and are required to fit in the limited space allowed by ... Read More
Turbulent Flow Around a Factory Chimney
Wind strakes on a chimney impede the uniform detachment along the height of the chimney, which can induce vibrations and eventually lead to fatigue at the footing of the chimney. A stationary turbulent flow simulation is computed for a chimney with strakes mounted on a factory building. ... Read More
Triaxial Test
The triaxial test is one of the most common tests used in laboratory soil testing. The soil sample is normally placed inside a rubber membrane and then compressed maintaining a radial pressure. In this model, a vertical displacement and a confinement pressure are applied on the sample ... Read More
Rotating Plate in a Unidirectional Molecular Flow
This model computes the particle flux, number density and pressure on the surface of a plate that rotates in a highly directional molecular flow. The results obtained are compared with those from other, approximate, techniques for computing molecular flows. Read More
Position Optimization of Grading Rings
Extending the High Voltage Insulator model, this example shows how to set up an Optimization Study to determine the optimum position of the grading rings to obtain the highest flashover voltage. Read More
k·p Method for Strained Wurtzite GaN Band Structure
This benchmark model computes the valence band structure of an unstrained and a strained bulk GaN wurtzite crystal, as a tutorial for users who wish to set up multiple wave function components with the Schrödinger Equation interface. The model follows the formulation given in the ... Read More
