Steel structures immersed in seawater can be protected from corrosion through cathodic protection. This protection can be achieved by an impressed external current or by using sacrificial anodes. The use of sacrificial anodes is often preferred due to its simplicity. This example models ... Mehr lesen
Some positive electrode materials are known to deteriorate in overcharged lithium-ion battery cells. Predominantly, manganese containing electrode materials such as LMO and NMC can loose capacity due to manganese dissolving from the materials at overcharge. This decomposition is a ... Mehr lesen
Deposition of metallic lithium on the negative electrode in preference to lithium intercalation is known to be a capacity loss and safety concern for lithium-ion batteries. Harsh charge conditions such as high currents (fast charging) and/or low temperatures can lead to lithium plating. ... Mehr lesen
For several high-precision applications, especially in hydraulic systems and fuel injectors, micro bores are needed. In most cases the shape of the injection hole, especially the edge rounding, has a significant influence on the atomization of fluids and therefore on the combustion ... Mehr lesen
This tutorial models a DC glow discharge by solving fluid-type plasma equations fully coupled with the homogeneous and time-independent electron Boltzmann equation in the classical two-term approximation. The approximated Boltzmann equation is solved for each position of space and is ... Mehr lesen
This tutorial simulates the turn-off transient (reverse recovery) of a simple PIN diode with an inductive load, loosely based on the book "Fundamentals of Power Semiconductor Devices" by B. J. Baliga (p. 256, 2008 edition). Unlike the book, which assumes an initial constant current ramp ... Mehr lesen
This tutorial uses a “black-box” approach to define a battery model based on a small set of lumped parameters, assuming no knowledge of the internal structure or design of the battery electrodes, or choice of materials. The input to the model is the battery capacity, the initial state ... Mehr lesen
This model shows how to combine an electric circuit simulation with a finite element simulation. The finite element model is an inductor with a nonlinear magnetic core and 1000 turns, where the number of turns is modeled using a distributed current technique. The circuit is imported ... Mehr lesen
This tutorial model explains how to extract lumped matrices by means of the Stationary Source Sweep study. The capacitance matrix of a five-terminal system is used to infer the position of a metallic object similar to real-world capacitive position sensors. The example illustrates the ... Mehr lesen
Many piezoelectric materials are ferroelectric. Ferroelectric materials exhibit nonlinear polarization behavior, such as hysteresis and saturation at large applied electric fields. In addition, the polarization and mechanical deformations in such materials can be strongly coupled due to ... Mehr lesen
