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.
Opto-acoustophoresis is a term used to describe the interplay between acoustics and optical fields. In most cases (including this) the optical field is heating up the material and therefore affecting the acoustic field. In this example of an acoustic trap a set of particle are trapped ... Read More
This example demonstrates an app that utilizes the LiveLink™ interface for Solid Edge® to run simulations on CAD designs. Read More
In this example, the etching of silicon in a CF4/O2 plasma reactor is studied using a global model. Parametric sweeps for ion energy and oxygen mole fraction are computed. Read More
This application illustrates a modeling approach for deriving physically consistent simplified models in the Acoustics Module. The approach consists of converting complex sub-components to an impedance boundary condition and otherwise using simple acoustics throughout the COMSOL model. ... Read More
This model computes the specific acoustic radiation impedance of a very small circular vent in a flanged configuration. The model includes thermoviscous losses. The radiation impedance is fitted using a simple RL circuit which gives a simple lumped representation. The results are used ... Read More
The problem of a plane wave scattering off a cylinder-shaped object suggests the use of the 2D axisymmetric formulation. This can save computation time and reduce the memory usage compared to the model in 3D space. This example demonstrates the use of the built-in plane wave expansion ... Read More
To understand the risk of coagulation and blood clot formation in an abdominal aortic aneurysm (AAA), modeling and simulation can be used to study the blood flow through the AAA. In this example, blood is modeled as an Oldroyd-B fluid. While this is a generic example, if instead using ... Read More
The "Smart Radiator Device," a multilayer structure, has the capability to control thermal emissivity at different temperatures. This multilayer structure is lightweight thus finds its application in spacecraft mission. The thermochromic vanadium oxide (VO2) material is the heart of ... Read More
A line array of eleven spherical hydrophones embedded in a neoprene coating is modeled in 3D. The sensitivity of the array is analyzed with regard to varying angles of incidence of the background pressure field. The array directivity function is computed and compared to the analytical ... Read More
Stimulated Brillouin Scattering (SBS) describes a nonlinear interaction between light and sound. In optical fibers, SBS can be detrimental for power or communication purposes, but can be leveraged for sensing applications. The SBS gain spectrum quantifies the optic-acoustic mode ... Read More
