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.
A 3D model is used to simulate the cooling of a bevel gear from an austenitic state. Phase material properties and phase transformation data are imported into the model. The final phase composition and the residual stress state are computed. Phenomena such as thermal strains, phase ... Read More
This benchmark models two-phase flow in a porous medium in 1D, where the flow can be analytically described by the Buckley-Leverett equation. Read More
This example demonstrates how modeling can be used to investigate the performance of different hydrodynamic journal bearings. The model uses the Hydrodynamic Bearing interface, which solves the Reynolds equation to compute the pressure developed in a thin fluid film for four bearing ... Read More
A cooling flange in a chemical process is used to cool the process fluid, which flows through the flange. The surrounding air cools the flange via natural convection. In the stationary model, the forced convection to the process fluid is modeled using a constant heat transfer ... Read More
This model demonstrates 3D topology and shape optimization for an extruded geometry. This can be achieved using equation-based modeling and extrusion operators. The model considers stiffness maximization of a beam subject to a constraint on the mass, but the method can be used with any ... Read More
Clearance between connected components is often introduced to facilitate assembly and allow relative motion. However, clearance in joints can generate impact forces that adversely affect system performance and lead to noise and vibration. This model compares the dynamic behavior of a ... Read More
This tutorial investigates the acoustic properties of a porous layer made of glass wool. The porous material has transverse isotropic properties and is modeled with the full anisotropic poroelastic material model. Read More
Due to the large differences in length scales in a lithium-ion battery, with the thickness of the different layers typically being several orders of magnitude smaller than the extension in the sheet direction, a lithium-ion battery is often well represented by a one-dimensional model. ...
