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 studies the stationary state of free convection in a cavity filled with water and bounded by two vertical plates. To generate the buoyancy flow, the plates are heated at different temperatures, bringing the regime close to the transition between laminar and turbulent. To ... Read More
This app demonstrates the following: Geometry parts and parametric geometries Dark theme Use of subwindows Material appearance visualization with environment reflections Report generation for both Microsoft® Word and Microsoft® PowerPoint Options for setting different mesh sizes ... Read More
This is a simple yet powerful simulation app for designing a two-dimensional reflective metalens. This metalens consists of a array of glass nanopillars on a metal substrate. Initially, the app determines the optimal grating parameters for a specific wavelength and calculates the ... Read More
This Application Gallery entry demonstrates how Far-Field radiation can be calculated when a substrate is present. Two approaches are demonstrated. A simplified form that works for two homogeneous domains, and a general approach that can handle multiple, inhomogeneous layers. This ... Read More
This model analyzes an RF MEMS switch consisting of a thin micromechanical bridge suspended over a dielectric layer. A DC voltage greater than the pull-in voltage is applied across the switch, causing the bridge to collapse onto the dielectric layer with a resulting increase in the ... Read More
In this model, the effect of corrosion product on galvanic corrosion between a magnesium alloy (AE44) and mild steel in contact with brine solution is presented, wherein deformed boundaries due to both deposition of corrosion product as well as dissolution of magnesium are considered. ... Read More
This model describes the evaporation of a droplet that consists of concentrated solution of acetone and water. It accounts for the coupled phenomena of chemical species transport and heat transfer over phase boundaries (liquid-gas boundary) as well as for multiphase flow. The droplet ... Read More
This is a benchmark model for the 2D axisymmetric formulation of the Electromagnetic Waves, Frequency Domain interface that is available with the RF Module. The problem is to find the resonant frequencies and fields inside an axisymmetric cavity with rectangular cross-section and ... Read More
This model simulates a temperature profile in a number of cells and cooling fins in a liquid-cooled battery pack. The model solves in 3D and for an operational point during a load cycle. A full 1D electrochemical model for the lithium battery calculates the average heat source. Read More
In this tutorial, the acoustic properties of a wax guard are analyzed. A wax guard is a small perforated mesh used to protect the receiver (the miniature loudspeaker in a hearing aid) used for receiver-in-the-ear (RITE) or receiver-in-canal (RIC) hearing aids. Because of the very small ... Read More
