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.
Turbulent flow, SSG-LRR interface is used to analyze fully developed turbulent flow in an axially rotating pipe and in a swirling jet emanating from such a pipe. The resulting flow pattern in the pipe is characterized by slower-than-solid-body rotation. Axial velocity of the swirling jet ... Read More
This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Inventor® via the LiveLink™ interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz. Read More
Nucleate boiling occurs when a liquid is heated by a source hotter than the saturated fluid temperature but with a heat flux below the critical heat flux. In this regime, high heat flux are possible due to the evaporation of the liquid. This model aims to demonstrate the calculation of ... Read More
The Helmholtz filter is a popular technique for imposing a minimum length scale in structural topology optimization, but certain applications also call for a maximum length scale. This model demonstrates how to achieve this using an extra PDE filter. Read More
In this example you will build and solve a 3D beam model using the 3D Beam interface. This model shows how a thermally induced deformation of a beam is modeled. Temperature differences are applied across the top and bottom surfaces as well as the left and right surfaces of the beam. ... Read More
A ribbon mixer (sometimes referred to as a ribbon blender) is a mechanical device that is commonly used to mix different types of granular material. Ribbon mixers are widely used across various industries including food processing, pharmaceuticals, chemical industries, agriculture, ... Read More
In this model, two fluids are separated by a multilayer solid elastic structure. An acoustic pressure wave impacts the structure resulting in a reflected wave and a transmitted wave with a loss through the structure. This model investigates the transmission loss through the structure. ... Read More
A steel ball is pressed down against a rubber membrane. When the contact pressure exceeds a certain value, the two parts start sticking together. When the ball is retracted, the membrane is pulled upwards in the bonded region. During the retraction, the bond is partially broken. This ... Read More
Formally known as size separation in vibrated granular materials, the Brazil nut effect (BNE) (and sometimes the Muesli effect) is a phenomenon that causes large grains to separate from small ones and rise to the top of a granular bed under vibrations. This phenomenon can be studied ... Read More
The present model demonstrates diffusion-controlled electrodeposition of copper on microstructured band electrode arrays (MEA). Mass transport by Fickian diffusion of copper ions is solved using the Transport of Diluted Species interface. Dendrite formation as a consequence of diffusion ... Read More
