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.
A spiral slot antenna provides a conformal design and can be used for communication, sensing, tracking, positioning, and many applications in different microwave frequency bands due to its wide-band frequency response. This model shows how to build a spiral geometry using parametric ... Read More
The marine controlled source electromagnetics method (CSEM) for oil prospecting has emerged as a promising technique during recent years. This model demonstrates one variant of it. It uses a mobile horizontal 1 Hz electric dipole antenna that is towed 150 m above the sea floor. An array ... Read More
The electron energy distribution function (EEDF) plays an important role in the overall behavior of discharges. In this example, the formation period of an Argon plasma is studied with special attention paid to the EEDF. The plasma is created within a 4 cm gap by a DC source voltage of 1 ... Read More
This model shows how to create dispersion diagrams from simulation results by extending the tutorial Thin-Film BAW Composite Resonator. The dispersion curve can be plotted against both real and imaginary values of the wave number, corresponding to the propagating modes and evanescent ... Read More
This model and tutorial demonstrates the use of an Application Method to compute and plot the geometric Modulation Transfer Function (MTF) for the Petzval Lens. Read More
Space charge limited emission is a phenomenon that restricts the current of charged particles that can be released from a surface. As the electron current released by a cathode increases, so does the magnitude of the charge density in the immediate vicinity of the cathode. This ... Read More
A double-ridged horn antenna is popularly used in anechoic chambers to characterize an antenna under test (AUT), from S-band to Ku-band, due to its reliable performance in a wideband frequency range. This tutorial models a double-ridged horn antenna and computes the voltage standing wave ... Read More
