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 example, a dynamic analysis of a three-cylinder reciprocating engine is performed to investigate stresses generated during operation, thereby permitting identification of the critical components. Demand for high power output relative to the weight of the engine requires careful ... Read More
This tutorial presents the averaging models available within the Heat Transfer in Porous Media interface, used to compute the effective thermal conductivity, when the local thermal equilibrium assumption is made. The models are compared for porosities ranging from 0 to 1, and for a ... Read More
Nucleate boiling occurs when a liquid is heated by a source hotter than the saturated fluid temperature but with a heat flux below the critical heat flux. In this regime, high heat flux are possible due to the evaporation of the liquid. This model aims to demonstrate the calculation of ... Read More
When high-fidelity measurement microphones are calibrated, a pressure reciprocity calibration method is used. During calibration, two microphones are connected at each end of a closed cylindrical cavity. For the calibration procedure, it is important to understand the acoustic field ... Read More
The present example simulates the steady-state flow in a radial pump using the mixing plane methodology. It solves for the averaged flow resulting from different blade positions of the rotor, thus circumventing the need to perform costly time-dependent simulations. Read More
Graphene, carbon atoms arranged in a two-dimensional hexagonal lattice has sparked tremendous research and application interests since its experimental discovery about two decades ago. Besides being ultrathin, this material exhibits a plethora of interesting properties, including high ... Read More
This non-conventional model of porous media flow utilizes creeping (Stokes) flow in the interstices of a porous media. The model comes from the pore-scale flow experiments conducted by Arturo Keller, Maria Auset, and Sanya Sirivithayapakorn of the University of California, Santa Barbara. ... Read More
This model and tutorial demonstrates the use of an Application Method to compute and plot the geometric Modulation Transfer Function (MTF) for the Petzval Lens. Read More
For more than 50 years, it has been known that neutrally buoyant particles in a flow channel tend to converge to specific locations in the channel cross section. For a cylindrical pipe, or two parallel planes carrying a Poiseuille flow, the equilibrium position is about 0.6 times the ... Read More
This model demonstrates the impact of convection and diffusion on the transport-limited electrodeposition of a copper microconnector bump (metal post). Microconnector bumps are used in various types of electronic applications for interconnecting components, for instance liquid crystal ... Read More
