This model addresses the concept of wireless power transfer by studying the energy coupling between two circular loop antennas tuned for UHF RFID frequency whose size is reduced using chip inductors. The circular loop antenna provides inherent inductive coupling by its shape, and it can ... Read More
This model shows how shape optimization can be used design the coils of an ICP reactor to obtain plasma uniformity. The reactor in study is a planar ICP with the coils distributed along the radial direction. The Optimization study step is used to find the best coil placement so that the ... Read More
An important and interesting phenomenon with supersonic flows are expansion fans, which take place when the flow encounters a convex or expansion corner. The direction of the flow changes smoothly across the fan, while the Mach number increases. This 2D example models an expansion fan ... Read More
This tutorial shows how you can use the Electromechanics interface in COMSOL's MEMS Module to model Electrostriction. Electrostrictive materials (e.g. PMN-PT) exhibit nonlinear strain as a function of electric field. This 2D axisymmetry model uses a parametric sweep of voltage to ... Read More
The shape of a log-periodic antenna resembles that of a Yagi-Uda antenna, but is composed of a coplanar array to achieve a wider bandwidth. It is also known as a wideband or frequency-independent antenna. All metallic parts are modeled using the perfect electric conductor (PEC) boundary ... Read More
This model simulates the isotropic compression of naturally structured and artificially structured clays using the Modified Structured Cam-Clay (MSCC) material model. The aim of the example is to reproduce the compression behavior given in a benchmark for four structured clays. Read More
Gyroscopes are used for measuring the orientation or maintaining the stability of airplanes, spacecraft, and submarines vehicles in general. They are also used as sensors in inertial guidance systems. This model demonstrates the modeling of a mechanical gyroscope. It analyzes the ... Read More
Trusses are commonly used to create light structures that can support heavy loads. When designing such a structure, it is important to ensure its safety. For a tower made of bars, buckling can cause the structure to collapse. This model shows how to compute the critical buckling load ... Read More
Failure of reinforced concrete structures involves advanced material behavior and interaction between materials. This example demonstrates how to model various stages of the failure of a reinforced concrete beam. The material model includes a coupled damage-plasticity model for the ... Read More
In this example, the coupling between Multibody Dynamics and Rotating Machinery, Magnetic for performing electromagnetic and mechanical analysis is demonstrated. A permanent magnet motor with 10 rotor poles and 12 stator slots is modelled in 2D. The magnets are attached to the ... Read More
