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 demonstrates the wrinkling of a thin rectangular sheet stretched uniaxially. First, a static analysis is performed to determine the region of negative principal stresses without wrinkling. Next, a prestressed buckling analysis is carried out to find out the linearized ... Read More
This model analyzes a piezoelectric microelectromechanical system (MEMS) speaker. The speaker, composed of four triangular membranes, uses a layer of lead zirconate titanate (PZT) material with two electrodes on top of a silicon layer as actuators. The triangular membranes are separated ... 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 model analyses the noise generated by an electric motor during its operation at different speeds of rotation. The type of electric motor analyzed, a permanent magnet synchronous motor (PMSM) uses permanent magnets in the rotor and a variable frequency current traveling through the ... Read More
Seawater intrusion is a critical issue in coastal regions, where it endangers both freshwater supplies and the overall quality of groundwater. This example showcases seawater intrusion in a coastal aquifer where a pumping well is located at some distance from the shoreline. The model ... Read More
This is a model of the heating process in a microwave oven. The distributed heat source is computed in a stationary, frequency-domain electromagnetic analysis. This is followed by a transient heat transfer simulation showing how the heat redistributes in the food. Read More
Shell-and-tube heat exchangers are commonly used in oil refineries and other large chemical processes. In this model, two separated fluids at different temperatures flow through the heat exchanger, one through the tubes (tube side) and the other through the shell around the tubes (shell ... Read More
The tonpilz (sound mushroom) piezoelectric transducer is a transducer for relatively low frequency, high power sound emission. The transducer consists of piezoceramic rings stacked between massive ends and pre-stressed by a central bolt. The tail and head mass lower the resonance ... Read More
Periodic microstructures are frequently found in composite materials, metallic foams, and sandwich structures. They can be described by a unit cell repeated along the three Cartesian directions. This app computes homogenized material properties of various periodic microstructures and ... Read More
This model analyzes the electromagnetic, mechanical, and acoustical characteristics of the OWS-1943T-8CP (discontinued) speaker. Beside certain details, the geometry, material properties, and measurements are copyright by Ole Wolff. Starting from the geometry of the speaker, an ... Read More
