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 tutorial model illustrates how to analyze the thermal effects of the sun as an external radiative source and considers wavelength-dependent surface emissivities. Specifically, the model features two coolers containing beverage cans that are exposed to ambient conditions and a beach ... Read More
This example describes the operation of a drug delivery system that supplies a variable concentration of a water soluble drug. A droplet with a fixed volume of water travels down a capillary tube at a constant velocity. Part of the capillary wall consists of a permeable membrane ... Read More
This tutorial demonstrates the operation of a gyroscope based on design provided by Dr. James Ransley at Veryst Engineering, LLC. The model uses the Electromechanics coupling with the mixed finite element formulation in the Electrostatics interface. 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 presents a homogenized model of a corrugated sheet based on a unit cell approach. The numerically obtained equivalent stiffness matrices are compared with various analytical models. Two corrugation profiles, trapezoidal and round, are considered in this example. Read More
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
The demand for phased array antennas increases not only for the traditional military industry but also in commercial areas such 5G mobile network platforms, Internet of Things (IoT), and satellite communication applications. This example shows how to design a phased array with a beam ... Read More
This example demonstrates a benchmark test showing that Electric Currents in Layered Shells physics interface can be used to obtain the same results as when the model is solved with the Electric Currents interface based on a solid 3D structure. Read More
Linear motors are used in many applications in need of translational motion. Typical characteristics of linear motor designs are high precision or quick acceleration. This model investigates a synchronous motor with three-phase winding on the stationary part and permanent magnets on the ... Read More
In this example, the coupling between Multibody Dynamics and Rotating Machinery, Magnetic for performing electromagnetic and mechanical analysis is demonstrated. A permanent magnet motor with 10 rotor poles and 12 stator slots is modelled in 2D. The magnets are attached to the ... Read More
