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. To download the MPH-files, log in or create a COMSOL Access account that is associated with a valid COMSOL license. 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 illustrates the modeling of slider motion caused by a base rotation. The motion of the slider is analyzed under various forces such as inertia force, centrifugal force, spring force and damping force. The prismatic joint, which is used to connect the two components, is spring ... Read More
Échelle spectrographs are commonly used in astronomy for high-resolution analyses of stellar atmospheres and for precision Doppler velocimetry. This tutorial simulates a "white pupil" form of this instrument. It makes use of several parts from the COMSOL Part Library and demonstrates the ... Read More
This tutorial model simulates a pair of straight conical bevel gears. The gears are modeled as rigid, but one of the gears is fixed while the other is hinged on a rigid bar. The rigid bar is also hinged at a point lying on the axis of the fixed gear. A transient analysis is performed to ... Read More
Some conventional three-port power dividers are resistive power dividers and T-junction power dividers. Such dividers are either lossy or not matched to the system reference impedance at all ports. In addition, isolation between two coupled ports is not guaranteed. The Wilkinson power ... Read More
This is a demonstration how to use the thermodynamics functionality in COMSOL to make flash calculations. * A flash calculation is an equilibrium calculation of a system where several species and phases are present at the same time. The system in this model is an azeotropic mixture ... Read More
The Whirling of a Uniform Shaft tutorial model shows you how to perform a transient analysis of a uniform shaft under gravity. The shaft is supported by two hydrodynamic bearings at its ends. The gyroscopic effect causes the rotor to whirl about its initial axis and the rotor eventually ... Read More
Walking instability, due to non-uniform distribution of clothes, is a common problem in lightweight portable washing machines. This problem is more severe in horizontal-axis washing machines, which are more popular because of their high efficiency in spite of high manufacturing cost. ... Read More
Experiments on dry and wet soil samples are performed to understand their behavior under different loading conditions. In this example, the Extended Barcelona Basic (BBMx) soil model is used to simulate the wetting and drying paths in partially saturated soil samples under cyclic ... Read More
This example models time-dependent copper deposition on a resistive wafer in a cupplater reactor. As the deposited layer builds up, the resistive losses of the deposited layer decreases. The benefit of using a current thief for a more uniform deposit is demonstrated. Read More
