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 demonstrates how to use the Polynomial Shell feature to increase the lowest Eigenfrequency of a shell by deforming its shape. Read More
This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in SolidWorks by using the LiveLink interface. Read More
In this model, two fluids are separated by a multilayer solid elastic structure. An acoustic pressure wave impacts the structure resulting in a reflected wave and a transmitted wave with a loss through the structure. This model investigates the transmission loss through the structure. ... Read More
Corrosion induced due to alternating current (AC) is evident in the oil and gas industry, particularly when a pipeline is in close proximity to the high power transmission lines. A numerical model presented here first evaluates the effect of direct current (DC) applied potential on ... Read More
In this tutorial model, you will see how to set up eigenfrequency and transient analyses (using FFT) of a rotor with various mountings and bearing supports. The example illustrates how to use Campbell and Waterfall plots to find the critical speed. It also demonstrates the range of ... Read More
This tutorial model demonstrates how to compute the impedance of a capacitively coupled plasma. The Time Periodic study computes the time periodic solution of the plasma. Subsequently, the solution is transformed to the time domain, after which the fast Fourier transform (FFT) solver is ... Read More
This is a model of a simple Sagnac interferometer consisting of two mirrors and a beam splitter arranged in a triangle. The entire modeling domain rotates; as a result, the rays propagating in opposite directions in the triangle have different optical path lengths due to the Sagnac ... Read More
This model shows how to calculate the lightning induced voltage of an overhead line over a lossy ground. Lightning channels with different inclinations are considered. The effect of soil conductivity is also shown. Read More
This example model consists of a two-hot-arm thermal actuator made of polysilicon. The actuator is activated through thermal expansion. The temperature increase required to deform the arms, and thus displace the actuator, is obtained through Joule heating (resistive heating). The greater ... Read More
This model demonstrates how to use the Free Shape Shell feature to increase the stiffness of a shell by deforming its shape. Read More
