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 tutorial example is kindly provided by Dr. James Ransley at Veryst Engineering, LLC. This model continues from the base model “A Micromachined Comb-Drive Tuning Fork Rate Gyroscope”, which is also provided by Dr. Ransley. The model demonstrates how to accurately compute the effects ... Read More
Frequency selective surfaces (FSS) are periodic structures with a bandpass or a bandstop frequency response. This model shows that only signals around the center frequency can pass through the periodic complementary split ring resonator layer. Read More
A wideband antenna study, such as an S-parameter or far-field pattern analysis, can be obtained by performing a transient response analysis and a time-to-frequency fast Fourier transform (FFT). This model runs a time dependent study first and then transforms the dependent variable, the ... Read More
A plane wave is incident on a reflecting hexagonal grating. The grating cell consists of a protruding semisphere. The scattering coefficients for the different diffraction orders are calculated for a few different wavelengths. Read More
This tutorial is a benchmark model that reproduces the Testing Electromagnetic Analysis Method (TEAM) Problem 32, which evaluates numerical methods for the simulation of anisotropic magnetic hysteresis. A hysteretic three-limbed laminated iron core is subject to a time-varying magnetic ... Read More
This model investigates the electrical and thermal characteristics of an inductively coupled plasma torch at atmospheric pressure. The discharge is assumed to be in local thermodynamic equilibrium. Read More
This tutorial performs steady-state and transient analysis of the response of a PIN diode to constant and pulsed radiation, respectively. The effect of radiation is modeled as spatially uniform generation of electron-hole pairs within the device. At high dose rates the separation of the ... Read More
This model shows how to set up a simple Bipolar Transistor model. The output current-voltage characteristics in the common-emitter configuration are computed and the common-emitter current gain is determined. Read More
This tutorial model solves for an inductively coupled plasma reactor in a mixture of SF6/argon. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. Read More
This model is a benchmark problem from TEAM workshop (problem 15 part I, see https://www.compumag.org/wp/team/). The model simulates the behavior of a coil as it scans a conductive plate containing a defect (a crack). The computed coil parameters, which include change in resistance and ... Read More
