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 single-phase induction motor model is used to compare with Testing Electromagnetic Analysis Method (TEAM) workshop problem 30. The Magnetic Fields physics interface is used to model the motor in the frequency domain at 60 Hz. The Velocity (Lorentz Term) feature is used to model the ... Read More
This tutorial studies the deposition of amorphous silicon using an inductively coupled plasma reactor with a silane/argon gas mixture. It examines how the deposition rate varies across the wafer as a function of silane mole fraction and input power. Read More
A microwave circulator is a multiport device in which a wave incident on Port 1 is coupled only into Port 2; a wave incident on Port 2 is coupled only into Port 3; and so on. Circulators are used to isolate microwave components, for example, to couple a transmitter and a receiver to a ... Read More
In this set of eight tutorial models and associated documentation, you can investigate the resistive, capacitive, inductive, and thermal properties of a standard three-core lead-sheathed XLPE HVAC submarine cable with twisted magnetic armor (500 mm2, 220 kV). The series includes a 2D, 2D ... Read More
This app demonstrates the following: Geometry parts and parameterized geometries Using tables for user input parameters Visualization on a 2D cross-section of a 3D geometry Improved visualization and user experience when a geometry object (the air object) is hidden. Induction heating ... Read More
The mutual inductance and induced currents between a single turn primary and twenty turn secondary coil in a concentric coplanar arrangement is computed using a frequency domain model. The secondary coil is modeled using a homogenized approach which does not explicitly consider each turn ... Read More
This example demonstrates a simulation setup for exciting surface plasmon polaritons using Otto and Kretschmann configurations. The underlying mechanism is enabled by the interplay between total internal reflection and evanescent-wave coupling phenomena. It also calculates the ... Read More
The mutual inductance and induced currents between a single turn primary and twenty turn secondary coil in a concentric coplanar arrangement is computed using a frequency domain model. Each turn of the secondary coil is modeled explicitly. The results are compared against analytic ... Read More
Tutorial example of the RF heating of passive conductive implants (rod and screws) inserted in three vertebrae during MRI. The RF fields are locally enhanced in the proximity of a passive conductive implant resulting in the heating of the portion of tissue facing the implant's surface. Read More
A mode analysis study is used to find the complex effective indices for a microstructured optical fiber (MOF), consisting of air holes in a silica host. As the effective index is smaller than the refractive index of the silica background material, the modes are leaky. The model ... Read More
