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 app simulates a micromixer based on an imported CAD geometry. The app shows how you can use the Application Builder to build an app that can handle CAD import and let the user interactively select boundary conditions. The app shows how this can be done without any programming using ... Read More
This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in SOLIDWORKS® by using the LiveLink™ interface with a parametric sweep. Read More
This tutorial model illustrates the use of the nucleate boiling heat flux features to compute the transient cooling of a cylindrical rod plated with nickel, and immersed in a pool of boiling water. The temperature and heat flux results obtained with a 3D time-dependent computation, with ... Read More
An acousto-optic modulator (AOM) is a device which can be used for controlling the power, frequency or spatial direction of a laser beam with an electrical drive signal. It is based on the acousto-optic effect, that is, the modification of the refractive index by the oscillating ... Read More
This example studies heat transfer in a composite two-dimensional structure. Four materials with distinct thermal conductivities k compose the structure. The top and bottom boundaries are facing environments respectively at 0°C and 20°C. The temperature distribution and the heat flux ... Read More
Zone electrophoresis (ZE) is an electrophoretic separation technique typically used for analyzing proteins, nucleic acids, and biopolymers. During the process, different species in a sample are transported in a continuous electrolyte buffer system, subject to a potential gradient. Due to ... Read More
This example uses the Electric Currents in Layered Shells interface and the Layered Shell interface to model a piezoresistive pressure sensor. The tutorial considers the design of the MPX100 series pressure sensors originally manufactured by Motorola Inc. Although the sensor is no ... Read More
This model presents the flow noise generated by flow past the so-called tandem cylinder configuration. The test is part of the “First Workshop on Benchmark problems for Airframe Noise Computations”. The tutorial model shows the steps involved in a flow-induced noise simulation in COMSOL ... Read More
This model demonstrates the transport of grains using a screw conveyor. The grains enter the conveyor through a chute and are transported over an incline by a rotating screw. This model also demonstrates how to build and run a model method that evaluates the mass flow rate. Read More
A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This example simulates splitting properties using a simplified 2D geometry. The geometry is optimized using shape optimization in order to get the ... Read More
