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.
Communication masts usually have a framework with a bolted triangular lattice design. The diagonals of the framework are assembled from several parts and welded together. When operating under a given wind load at a specific location, the antenna’s total rotation angle should stay below ... Read More
Bearings are used in machines to reduce the friction between moving parts and thereby smooth their relative motion. Rolling element bearings are one of the most widely used bearings, where rolling elements or rollers are used to support the load. These rollers can be of different shapes; ... Read More
This example shows how to set up a piezoelectric transducer problem following the work of Y. Kagawa and T. Yamabuchi. The composite piezoelectric ultrasonic transducer has a cylindrical geometry that consists of a piezoceramic layer, two aluminum layers, and two adhesive layers. The ... Read More
This tutorial application demonstrates the modeling of a hinge joint between two bodies in COMSOL Multiphysics. Various nodes available for joints such as Constraints, Locking, Spring, Damper, Prescribed Motion, and Friction are also demonstrated. Many real structures can be ... Read More
In a lithium metal battery, lithium metal is deposited during charging on the negative electrode. Mass transport and ohmic effects in the electrolyte cause small protrusions on the metal surface to be subjected to accelerated growth during charging. In worst case scenarios, this leads to ...

See how to perform a vibration analysis of the crankshaft of a 3-cylinder reciprocating engine in this tutorial model. Due to the eccentricity of the crank-pin and balance masses on the crankshaft, it undergoes self-excited vibration under rotation. The crankshaft is modeled using solid ... Read More
The example shows a 1D steady-state thermal analysis including radiation to a prescribed ambient temperature. The temperature field from the solution of this benchmark model is compared with a NAFEMS benchmark solution. Read More
This model investigates the electrical and thermal characteristics of an inductively coupled plasma torch at atmospheric pressure. The discharge is assumed to be in local thermodynamic equilibrium. Read More
In static mixers, also called motionless or in-line mixers, a fluid is pumped through a pipe containing stationary blades. This mixing technique is particularly well suited for laminar flow mixing because it generates only small pressure losses in this flow regime. This example studies ... Read More
A plane electromagnetic wave propagating through free space is incident at an angle upon an infinite dielectric medium. This model computes the reflection and transmission coefficients and compares to the Fresnel equations. Read More
