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.
This example demonstrates the modeling of a sandwiched composite blade made up of carbon–epoxy, glass–vinylester, and PVC foam materials. Three different methods are used to model the sandwich composite structure: Layerwise theory, Equivalent Single Layer (ESL) theory, and a multiple ... Read More
This example of a simple axisymmetric condenser microphone includes all the relevant physics and determines the microphone sensitivity as well as microphone capacitance for the specific simplified microphone geometry and material parameters. It solves a fully coupled multiphysics model ... Read More
This model shows how to combine an electric circuit simulation with a finite element simulation. The finite element model is an inductor with a nonlinear magnetic core and 1000 turns, where the number of turns is modeled using a distributed current technique. The circuit is imported ... Read More
In this tutorial example, the concepts of Component Mode Synthesis (CMS) are introduced through a simple solid model of a cantilever beam. Parts of the beam are reduced by the CMS technique. It is, furthermore, shown how CMS can be used to represent both the static and dynamic behavior ... Read More
Delamination or the separation of layers is a common failure mode in laminated composite materials. Various factors, including loading, defects in the material, and environmental conditions can trigger the initiation and propagation of layer separation. This leads to degraded structural ...

Induced eddy currents and associated thermal loads is of interest in many high power AC applications. This example is of general nature and illustrates some of the involved physics as well as suitable modeling techniques in the AC/DC Module. In this model a metallic plate is placed ... Read More
This model illustrates the modeling of temperature distribution in a simplified mixer. Read More
This model addresses the concept of wireless power transfer by studying the energy coupling between two circular loop antennas tuned for UHF RFID frequency whose size is reduced using chip inductors. The circular loop antenna provides inherent inductive coupling by its shape, and it can ... Read More
Vibration and noise in washing machines, due to the non-uniform distribution of clothes in the barrel, is a common problem worth studying and optimizing for. This model simulates a multibody dynamics model of a horizontal-axis portable washing machine. An eigenfrequency analysis is ... Read More
This model simulates vibrations in a compound gear train. Spur gears, used to model the gear train, are mounted on rigid shafts. The shafts are supported by an elastic housing at both ends. The gear mesh is assumed to be elastic with varying stiffness, which is the source of vibration. A ... Read More
