Layered shell elements, which are used for modeling composite shells, often connected to solid and shell elements in cladding or side-by-side configuration to represent a realistic structure. For such applications, it becomes important to connect layered shell element correctly and ... En savoir plus
Multipaction can occur when electrons are accelerated by a high frequency RF field into surfaces. At certain frequencies, the number of electrons in a cavity can grow exponentially. This exponential growth cannot continue indefinitely because space charge effects in the cavity can ... En savoir plus
This tutorial shows how to model transport of the individual ions in a salt melt comprising two binary salts, where the transport equations are defined using concentrated solution theory. The example model defines a molten carbonate fuel cell (or electrolyzer), with a 1D-model geometry ... En savoir plus
A battery’s possible energy and power outputs are crucial to consider when deciding in which type of device it can be used. A cell with high rate capability is able to generate a considerable amount of power, that is, it suffers from little polarization (voltage loss) even at high ... En savoir plus
Induction pumps are used in high temperature cooling systems. The principle of operation is equivalent to a linear three phase induction motor. The lack of moving parts and the pumped liquid being kept in a hermetically closed system are clear advantages. This model shows how to simulate ... En savoir plus
The first part of the application computes the modes for a straight step index fiber made of silica glass. In the second part, a step index fiber bend with a 3 mm radius of curvature is analyzed with respect to propagating modes and radiation loss. It is shown how to find the power ... En savoir plus
Passive devices can be designed using lumped element features if both the operating frequency of the device and the insertion loss of lumped elements are low. This example simulates two types of lumped element filters that are similar to lumped ports, except that they are strictly ... En savoir plus
Frequency-selective surfaces (FSS) are periodic structures with a bandpass or a bandstop frequency response. This model shows that only signals around the center frequency can pass through the periodic complementary split ring resonator layer. En savoir plus
Electrical events, such as an overcurrent or overload, can seriously damage electrical circuits or power lines. To avoid expensive replacements of critical parts, electric switch circuit breakers can be installed. These mechanically interrupt the current flow or surge by moving a plunger ... En savoir plus
This example analyzes the deformation of a feeder clamp under stress. The clamp secures a feeder that carries high-frequency electromagnetic fields, and it’s important that it remains as straight as possible. Forces on the clamp include both those from the feeder as well as those on the ... En savoir plus
