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.
When a valve is closed rapidly in a pipe network it gives rise to a hydraulic transient known as a water hammer. The propagation of these hydraulic transients can in extreme cases cause failures of pipe systems caused by overpressures. This is a model of a simple verification pipe system ... Read More
This model tracks a contaminant that enters an aquifer at a point, such as an injection well or toxic spill, and spreads through the aquifer with time. The model has an analytic solution developed by Wilson and Miller. This analytic solution has been used to test several dedicated fluid ... Read More
The heat exchanger in this tutorial model contains a dynamic wall with an oscillating wave shape. The deformation induces mixing in the fluid and reduces the formation of thermal boundary layers. Hence, it increases heat transfer between the walls and the fluid. In addition, the wave ... Read More
This example compares moisture transport within two types of anisotropic porous medium. The first component defines a layered structure. The structure alternates between layers with high and low moisture diffusivity. So the moisture spreads more easily along the layers than transversely. ... Read More
The aerodynamic properties of a wing, propeller, or turbine blade are to a large extent determined by the precise shape of the airfoil that is used. The NACA Airfoil Optimization application computes the two main aerodynamic properties (the lift and drag coefficients) of a fully ... Read More
This tutorial illustrates how to use built-in variables and operators, for the evaluation of the bulk temperature along a geometry like a channel, a pipe or a chimney, in a nonisothermal flow in 2D and 3D. The bulk temperature may be needed to compute the heat transfer coefficient for an ... Read More
Digital Rock technology utilizes high-resolution imaging techniques, such as SEM and X-ray CT, to characterize the pore structures of rock cores. This approach enables pore-scale modeling of reservoir rocks, offering valuable insights into pore morphology, connectivity, and fluid ... 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
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
This model demonstrates how to set up a fully coupled poroviscoelastic model of biological tissues. The model is benchmarked by simulating a cyclic uniaxial tension–compression test on human brain tissue. Read More
