This model simulates a simple three-dimensional axisymmetric Helmholtz resonator, a classic acoustics model of a resonating circuit with a known theoretical solution. The idealized version considered here consists of a tube and a closed volume in series which are exposed to a pulsatile ... Mehr lesen
Permanent magnet bearings are used in turbomachinery, pumps, motors, generators, and flywheel energy storage systems, to mention a few application areas; contactless operation, low maintenance, and the ability to operate without lubrication are some key benefits compared to conventional ...

This model simulates the propagation of a positive streamer in a weak electric field where the process of photoionization is essential to provide seed electrons at the front of the streamer head. The simulated electric field and electron density as a function of time agree well with that ... Mehr lesen
A plane electromagnetic wave is incident on a metallic sphere partially embedded on a substrate. In this electromagnetic scattering problem, the far-field variables are computed for a few elevation angles of incidence. Mehr lesen
A cylindrical magnet falling through a copper tube induces eddy currents on the tube walls, which in turn, create a magnetic field that opposes the magnetic field of the magnet and induces a braking force that opposes the motion of the magnet. This model computes the velocity of the ... Mehr lesen
The example shows how to generate a discharge model from the Reaction Engineering interface with a self-defined discharge chemistry. It reproduces the library model 127181 (Double-Headed Streamer in Parallel-Plate Electrodes). Mehr lesen
This example simulates the propagation of a positive streamer in transformer oil under a lightning impulse voltage. The space charge density and the electric field are obtained. The simulated streamer radius agrees well with the measured values. Mehr lesen
This example shows how to use the Optimization Module to find a coil geometry giving a uniform magnetic field on axis and minimal field near the axis ends. Mehr lesen
A vessel traveling on the surface or under water gives rise to detectable local disturbances in the Earth’s magnetic field. These disturbances can be used to trigger weapon systems. The magnetic signature of a ship can be reduced by generating a counteracting magnetic field of suitable ... Mehr lesen
This tutorial model solves the Gross–Pitaevskii Equation for the ground state of a Bose–Einstein condensate in a harmonic trap, using the Schrödinger Equation interface in the Semiconductor Module. The equation is essentially a nonlinear single-particle Schrödinger Equation, with a ... Mehr lesen
