Superconducting materials have zero resistivity up to a certain critical current density, above which the resistivity increases rapidly. To model such a material, this example uses the Magnetic Field Formulation physics interface. The model was based on a suggestion by Dr. Roberto ... Mehr lesen
This model shows a setup of two parallel wires with a constant current running through both. Their cross-sections are successively reduced until a set force per unit length is reached. Mehr lesen
Silicon carbide (SiC) epitaxial furnaces are a specialized equipment for the production and preparation of SiC epitaxial wafers. This example model demonstrates the process of preparing an SiC epitaxial wafer based on the physical vapor transport (PVT) method in a furnace. This involves ... 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
The mutual inductance between a primary and secondary single turn coil in a concentric coplanar arrangement is computed using a DC, steady-state, model and compared against the analytic solution. The induced currents in the secondary coil are computed using an AC, frequency-domain, ... Mehr lesen
A transient model of a capacitor is solved in combination with an external electrical circuit. The finite element model of the capacitor is combined with a circuit model of a voltage source and a resistor. A step change in voltage is applied, and the transient current through the ... Mehr lesen
The principle component of a quadrupole mass spectrometer is the mass filter which is used to filter ions with different charge to mass ratios. The quadrupole mass filter has been well studied over the years, Ref. 1 and the physics and optimal design are well understood. In a real ... Mehr lesen
The models here showcase several use cases of the Circuit Extractor add-in, which is able to generate electric circuits from solved physics. A more detailed description of this tutorial model can be found in the blog post "Extracting Electrical Circuits from Electromagnetics ... 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 ...

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
