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 model simulates the dynamics of a shock absorber used in an aircraft landing gear mechanism. It analyzes the stresses and heat generated in the landing gear components due to energy dissipated by the shock absorber. A prismatic joint with a spring and damper is used to model the ... Read More
As integrated circuit (IC) technology advances, with circuits becoming more powerful and compact, it is increasingly important to identify and prevent any cause of circuit failure. One particularly critical factor contributing to circuit failure is electromigration within the ... Read More
This example illustrates the modeling and dynamic analysis of a three-cylinder reciprocating engine. The model combines rigid and flexible components to investigate engine performance and the stresses generated during operation. The analysis helps identify critical components and ... Read More
Composite materials are often used in structural applications because their properties, such as stiffness and strength, can be tailored to meet specific requirements. This makes them attractive alternatives to traditional engineering materials. Composites are also used in applications ... Read More
This example shows a 2D steady-state thermal analysis including convection to a prescribed external (ambient) temperature. It is given as a benchmarking example. The benchmark result for the target location is a temperature of 18.25 C. The COMSOL Multiphysics model, using a default mesh ... Read More
This example describes an array of heating tubes submerged in a vessel with fluid flow entering at the bottom. This is a multiphysics model because it involves fluid dynamics coupled with heat transfer. The pressure and the velocity field are the solution of the Navier-Stokes equations, ... Read More
The example shows a 1D steady-state thermal analysis including radiation to a prescribed ambient temperature. The temperature field from the solution of this benchmark model is compared with a NAFEMS benchmark solution. Read More
This is a benchmark model for an axisymmetric transient thermal analysis. The temperature on the boundaries changes from 0 degrees C to 1000 degrees C at the start of the simulation. The temperature at 190 s from the anlysis is compared with a NAFEMS benchmark solution. Read More
This model approximates 3D spherical transport using a 1D model. Many models of industrial-transport problems allow the assumption that the problem is spherically symmetric. This assumption is of great importance because it eliminates two space coordinates to result in a 1D problem that ... Read More
In nuclear fusion reactors, the conducting fluid, such as the fusion plasma and the liquid metal in the reactor blanket, will interact with the background magnetic field. This phenomenon is referred to as magnetohydrodynamics (MHD). The electromagnetic field and fluid flow are fully ... Read More
