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.
Drying of porous media is an important process in the food and paper industry among others. Many physical effects must be considered: fluid flow, heat transfer with phase change, and transport of participating liquids and gases. All of these effects are strongly coupled, and predefined ...

This is a model of a moving-coil loudspeaker where a lumped parameter analogy represents the behavior of the electrical and mechanical speaker components. The Thiele-Small parameters (small-signal parameters) serve as input to the lumped model, which is represented by an Electric Circuit ... Read More
A cable is a structural member which has stiffness only in its tangential direction, but virtually no bending stiffness. When supported only at its two ends it deflects under gravitational load forming a curve known as catenary. This example shows how to model components such as cables, ... Read More
This is a benchmark model to test the numerical algorithms in the area of multibody dynamics. This model simulates the dynamic behavior of the slider crank mechanism. This mechanism goes through singular positions during its operation. The acceleration at a point is compared with the ... Read More
The electrochemical cell shown in this model can be regarded as a unit cell of a larger wire-mesh electrode that is common in many industrial processes. One of the most important aspects in the design of electrochemical cells is the current density distributions in the electrolyte and ... Read More
This suite of examples illustrate the modeling of selective NO reduction, that occurs as flue gases pass through the channels of a monolithic reactor in the exhaust system of a motored vehicle. The simulations are aimed at finding the optimal dosing of NH3, the reactant that serves as ... Read More
This example explores the shift in natural frequencies caused by changing the temperature. One study investigates a doubly clamped beam where both ends are fixed, while the other study looks at a cantilever beam where only one end is fixed. The following effects are studied: Stress ... Read More
This model illustrates the dynamics of helical gears. It is built using the gears functionality in the Multibody Dynamics interface in COMSOL Multiphysics. A transient study is performed to analyze the effect of constant gear mesh stiffness, varying gear mesh stiffness, and the ... Read More
The dynamic response of a human body in any vibration environment can be predicted using this biomechanical model. In the automobile industry for instance, this model can be used in ride quality simulation and designing vibration isolators such as seats. In this example, a ... Read More
This model provides you with tools to build a variety of mixers by combining two common types of vessels with two types of impellers. The mixers are baffled flat and dished bottom vessels with either pitched blade impellers or Rushton turbines. The model includes three examples using the ... Read More
