This tutorial model shows how to model a structure using both shells and solids, and how to create the transition between them. Results are compared between the shell solution and the full 3D solution, and the effects of the transition are highlighted. Mehr lesen
This model computes the transmission probability through an RF coupler using both the angular coefficient method available in the Free Molecular Flow interface and a Monte Carlo method using the Mathematical Particle Tracing interface. The computed transmission probability determined by ... Mehr lesen
In small PEM fuel cell systems (in the sub-100 W range) no active devices for cooling or air transport are normally used. This is due to the desire to minimize parasitic power losses from pumps and fans, and to reduce the system complexity, size, and cost. The reactants at the cathode ... Mehr lesen
Wind strakes on a chimney impede the uniform detachment along the height of the chimney, which can induce vibrations and eventually lead to fatigue at the footing of the chimney. A stationary turbulent flow simulation is computed for a chimney with strakes mounted on a factory building. ... Mehr lesen
When a conductive solid material moves through a static magnetic field, an eddy current is induced. The current that flows through the conductor, which is itself moving through the magnetic field, induces a Lorentz force back on the solid. Therefore, a conductive solid that is vibrating ...

When analyzing rotors, it is common that bearings are modeled through their effective dynamic coefficients about a static equilibrium position. This model illustrates how to compute such coefficients for a cylindrical journal bearing. The bearing length is kept much smaller than its ... Mehr lesen
This type is one of the most popular laser cavities. In particular, it is often used for the Ti-doped sapphire femto-second laser. The stability of the laser cavity is analyzed by releasing a ray inside the cavity and is traced for a predefined time period that is sufficiently long. ... Mehr lesen
Biconical antennas are popular for very high frequency (VHF) measurement because they support a wide frequency range. They are also useful for electromagnetic compatibility (EMC) testing where the antenna can be used as an RF source in susceptibility or immunity test. This model ... Mehr lesen
This model computes the trajectory of an ion in a uniform magnetic field using the Newtonian, Lagrangian and Hamiltonian formulations available in the Mathematical Particle Tracing interface. Mehr lesen
A radio frequency quadrupole ion trap utilizes a radio frequency quadrupole (RFQ) in order to trap an ion beam. A continuous high energy ion beam is first cooled and converted into a spatially confined bunch, which can then be released with minimal heating of the beam. The device is also ... Mehr lesen
