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.
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
A journal bearing is composed of an outer cylinder (bearing) wrapped around an inner rotating journal (shaft), with a lubricant separating the two. Under certain operating conditions, cavitation can occur between the bearing and the journal, leading to component damage and failure. ... Read More
This is a small 2D demonstration model that couples the Linearized Navier-Stokes, Frequency Domain, Solid Mechanics, and Turbulent Flow (k-epsilon) physics interfaces to model the vibrations of a plate located in a 2D viscous parallel plate flow. This type of model is used to model fluid ... Read More
This tutorial model can be used to learn how to calculate mass and energy balances. Get a detailed demonstration in this blog post: How to Calculate Mass Conservation and Energy Balance Read More
This example describes how to simulate the flow of a thin film of fluid in the gap between two rectangular plates, one of them with a porous facing, when the fluid is squeezed as a consequence of the relative motion between the plates. The model accounts for the ingress and egress of ... 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
This setup demonstrates how the characteristics of turbulent flow in a channel are modified by the presence of an adjacent porous region. Asymmetric velocity profiles, higher turbulence levels, and higher friction coefficients both at the solid wall and the fluid-porous interface are ... Read More
You can use assembly meshing to reduce the number of mesh elements in your model, which is especially useful for conjugate heat transfer simulation in cases where the fluid domains can be handled with swept mesh. These models demonstrate how to use form assembly and discontinuous meshes ... Read More
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 benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic slider bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. Read More
