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 tutorial model, a step thrust bearing is topology optimized to maximize the bearing capacity. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to be ... Read More
In his example, the lowest natural frequency of a 3D bracket are maximized using shape optimization. Read More
Shape optimization with respect to fatigue properties is not supported, but fatigue properties are well correlated with the maximum stress. The model demonstrates how optimization with respect to a p-norm of the von Mises stress can be used to improve fatigue properties without ... Read More
This model demonstrates how to use the Polynomial Shell feature to increase the lowest Eigenfrequency of a shell by deforming its shape. Read More
This model performs a topological optimization for a Tesla microvalve. A Tesla microvalve inhibits backwards flow using friction forces rather than moving parts. The design can be optimized by distributing a specific amount of material within the modeling domain. The goal is to maximize ... Read More
Topology optimization of the Navier-Stokes equations is encountered in different branches and applications, such as in the design of ventilation systems for cars. A common technique applicable to such problems is to let the distribution of porous material vary continuously. In this ... Read More
The pyrolysis of a centimeter-sized wood particle presents a fully coupled multiphysics problem with mass transfer, fluid flow, and heat transfer. This example model consists of two parts. The first part demonstrates how to set up a model describing the pyrolysis of a porous, ... Read More
The suspension of a loudspeaker is designed to keep the membrane in place and avoid any rocking movement of the voice coil. At low frequencies, where the displacement of the membrane is significant, the stiffness of the suspension varies along the movement of the voice coil. This ... Read More
