Multi-Turn Coil Winding around a Ferromagnet - new

A demo model of a 50 Hz AC coil wound around a ferromagnetic (linear) core. The model is intended as a tutorial to show how to create a relatively complex geometry and set up the new Multi-Turn Coil features for the simulation. The model requires the Design module to fillet the edges of the block.

Vector Hysteresis Modeling

Hard ferromagnetic materials are often used as cores in inductive devices. These materials exhibit hysteresis, which means that the magnetization of the material not only depends on the magnetic field, but also on the previous state of magnetization. In order to use these materials in time-dependent simulations, hysteresis modeling is required. In this model, a 3D simulation employing the ...

Transmission Line Calculator

The transmission line parameters R, L, G and C are used to characterize any TEM and quasi TEM waveguide structure. This application computes R, L, G and C as well as the characteristic impedance and propagation constant for some common types of transmission lines.

Ion Funnel

An electrodynamic ion funnel provides an efficient means of transferring ions from regions of high pressure to high vacuum. The ion funnel can couple devices which generally operate at pressures of different orders of magnitude, such as ion mobility spectrometers and mass spectrometers, allowing mixtures of ionized gases to be separated and analyzed while minimizing losses. This model ...

Relativistic Diverging Electron Beam - new

When modeling the propagation of charged particle beams at high currents and relativistic speeds, the space charge and beam current create significant electric and magnetic forces that tend to expand and focus the beam, respectively. The *Charged Particle Tracing* interface uses an iterative procedure, in this example, to efficiently compute the strongly coupled particle trajectories and ...
