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.
Microlaboratories for biochemical applications often require rapid mixing of different fluid streams. At the microscale, flow is usually highly ordered laminar flow, and the lack of turbulence makes diffusion the primary mechanism for mixing. While diffusional mixing of small ... Read More
Multilateral wells—those with multiple legs that branch off from a single well—can produce oil efficiently because the legs can tap multiple productive zones and navigate around impermeable ones. Unfortunately, drilling engineers must often mechanically stabilize multilateral wells with ... Read More
This model shows how to build and solve a radiative heat transfer problem using the Heat Transfer interface. In particular, this 2D model illustrates the use of the surface-to-surface radiation feature. In this model, three surfaces form a cavity. Heat flux is set at two outer ... Read More
This model represents a stove in a living room. A radiation study is performed with the Surface-to-Surface Radiation physics interface. It shows the intensity of the stove radiation received on different surfaces of the room. Read More
During quenching of steel, austenite decomposes into phases such as ferrite, pearlite, bainite, and martensite. A common way to illustrate the phase transformation characteristics of a particular steel alloy is to use transformation diagrams. Two of the most commonly used diagram types ... Read More
Ponds and lakes can serve as thermal reservoirs in geothermal heating applications. In this example, fluid circulates underwater through polyethylene piping in a closed system. The pipes are coiled in a slinky shape and grouped onto sleds. The Non-isothermal Pipe Flow interface sets up ... Read More
The heat transfer rate and hydraulic resistance of a three dimensional heat exchanger is optimized in the laminar flow regime. Read More
This is a tutorial model of the coupling between flow of a fluid in an open channel and a porous block attached to one of the channel walls. The flow is described by the Navier-Stokes equation in the free region and a Forchheimer-corrected version of the Brinkman equations in the porous ... Read More
