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 example computes the effectiveness of a porous microchannel heat sink over a conventional microchannel heat sink. The model is fully parameterized. A parameter study on the thickness of the porous substrate is used to determine the optimal configuration. Read More
This model shows how to simulate a capacitively actuated surface micromachined accelerometer, using the Electromechanics Interface. It is based on a case study from the book Microsystem Design by Stephen D. Senturia (Kluwer Academic Publishers, 5th Edition, 2003, pages 513-525). Read More
The purpose of this model is to introduce the specular reflection in Surface-to-Surface Radiation using the ray-shooting algorithm. Different parameters are available to the user to yield better accuracy in the results when using the ray-shooting algorithm. The model is a standard ... Read More
This tutorial example of the pasta extrusion process shows how to simulate the non-isothermal flow of dough in the metering zone of a pasta extruder accounting for the temperature dependent material properties of the hydrated semolina dough. Read More
Modeling flow through realistic porous structures is difficult due to the complexity of the structure itself. Often, resolving the flow field in detail is not feasible; therefore, a macroscopic description of the pore scale structure, which utilize averaged quantities such as porosity ... 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
In a polymer electrolyte membrane water electrolyzer cell, hydrogen and oxygen gas is produced by electrolysis. The hydrogen and oxygen compartments are separated by a polymer membrane, that also acts as electrolyte. This introductory tutorial computes the ohmic and activation losses in ... Read More
The inductor is a common component in a variety of electrical devices. Its applications include power transformation and measurements, and it can also be used together with capacitors to create oscillators. In small devices with many components, such as in laptops, heat generation can ... Read More
Nowadays, there is a trend to manufacture wheel rim made up of a composite material instead of aluminum. The primary reason is to have lower values of unsprung mass which leads to faster response time and thus better acceleration, braking and cornering performances. Typically a carbon ... Read More
The bidirectional formulation of the Beam Envelopes interface can be used not only for counter-propagating wave simulations but also for waves propagating to up to two directions. In this model, an almost collimated Gaussian beam is excited at the left boundary and exhibits total ... Read More
