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 shape 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
A waveguide filter is designed using shape optimization by moving and scaling rectangles in the geometry. The irises of the initial geometry are optimized to ensure good bandpass response and out-of-band rejection, while maintaining the double mirror symmetry. Read More
Topology optimization can result in novel designs due the extreme design freedom associated with the method. Conventional manufacturing techniques impose constraints on the geometry which are often violated by topology optimization. This model demonstrates how the milling constraint ... Read More

The mass of an aluminum beam is minimized subject to a displacement constraint and a distributed load. The problem is solved using topology optimization with milling constraints. Read More
This example solves the problem of finding the optimal thickness profile of a flywheel, so that the moment of inertia is maximized without increasing the mass or the maximum stress in the flywheel. Read More
This model demonstrates how to find the optimal size and position of a water pipe in an air chamber, so that the energy absorption in the water is maximized. The objective is implemented as a constraint, so that the optimization terminates, when the desired performance is achieved. Read More
Extending the Tuning Fork model, this example shows how to set up an Optimization Study to determine the prong length at which the fork vibrates at the standard concert pitch, 440 Hz. Read More
Buckling is a common failure mode for slender structural components. This model shows how the buckling load of a diagonal brace can be maximized, while constraining the volume of the brace. Read More
