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.
Tesla microvalves exploit the non-linear nature of inertial flow to create anisotropic flow resistance. They can be used as robust valves owing to their passive working mechanism, but for many applications the diodicity is too low. Two-dimensional simulations and optimization over ... Read More
This tutorial model demonstrates the use of the multiphysics coupling feature Thermal Connection, Layered Shell, Edges. In this model, three layered shells are connected to heat domains by edges at difference locations related to the heat domains. The results obtained with the Heat ... Read More
This tutorial model demonstrates the use of the features for heat transfer in layered shells, to account for the curvature of the layers when applying heat fluxes and heat sources. The results obtained with the Heat Transfer in Shells interface applied to a boundary (with extra ... Read More
Fluence rate is a key parameter for ultraviolet (UV) water purifier. It describes the amount of radiation that pathogens absorb and is then directly related to the disinfection level of the purifier. The aim of this example is to demonstrate the fluence rate calculation with the ... Read More
This tutorial demonstrates how to use the temperature and relative humidity computed by the simulation of heat and moisture transport in an insulated roof as inputs for a mold prediction model. The VTT model for mold growth and decline prediction computes a mold index M by solving an ... 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
In this example, a heat transfer model of a fiber composite's unit cell is analyzed with the Cell Periodicity feature. The homogenized thermal conductivity, density and heat capacity of a composite material are computed based on the individual properties of fiber and matrix. A comparison ... Read More
Many important processes in the mesoscale can be described by phase-field models. One of the oldest phase-field problems is the spinodal decomposition. Several standardized benchmark problems have been developed by the phase-field community. In this entry, these problems are solved using ... Read More
