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.
Electromagnetic analysis of a 400kVA, 15kV/400V three-phase power transformer with Y-d connection and multiple primary and secondary coils with hundreds of turns. The model features the standard open- and short-circuit test in 2Daxi and 3D simulations to estimate electrical quantities ... Read More
This model uses the Semiconductor and RF modules to describe a photoconductive antenna (PCA). A laser pulse is applied on the surface of undoped LT-GaAs to generate electron-hole-pairs, which move under the influence of an external E-field creating a transient electric current pulse. ... Read More
This model exemplifies the analysis of strong wind flow around a solar panel and the corresponding structural displacement due to the wind's load. The solar panel is located in an array of equally spaced identical panels, which allows for the assumption that the periodic flow conditions ... Read More
This model demonstrates the simulation of surface dielectric barrier discharges (DBDs) using the Electric Discharge interface. The formulation incorporates a comprehensive set of physical processes, including charge transport, impact ionization, electron attachment, recombination, and ... Read More
This model deals with electrohydrodynamics (EHD), where a charge separation on the phase boundary between a liquid and air involves the formation of a charged layer. This charged layer allows for a net force to be induced at the interphase when a large electric field is applied. The ... Read More
Basin-type insulators are essential components in Gas-Insulated Metal-Enclosed Switchgear (GIS). During manufacturing, the epoxy resin curing process can generate residual stresses that may lead to crack formation. Over time, such cracks can trigger partial discharges, degrading the ... Read More
This model shows how to model an electrolyte-gated organic field-effect transistor based on a general drift–diffusion model. The model uses the Transport of Charge Carriers interface and the Electrostatics interface. The transistor characteristics are visualized. Formation of the EDLs in ... Read More
This model evaluates the temperature distribution in 3 buried cables in a situation where the soil surface temperature is known. The temperature profile obtained with a thermal circuit approach for the cables is compared with a FEM approach. The thermal circuit properties are established ... Read More
Oxide jacking is the process by which reinforced concrete cracks, due to the corrosion of the reinforcing rebar rods. The corrosion process causes growth of an oxide layer on the rebar, which in turn causes internal stresses in the concrete. If the corrosion process is allowed to ... Read More
This model captures the dynamic resistive switching behavior of an oxide-based memristor. The device features a thin metal oxide layer sandwiched between two metal electrodes. When a voltage is applied, oxygen vacancies within the oxide layer migrate, acting as charge carriers and ... Read More
