Copper electrowinning is the process of copper extraction from an electrolyte solution and its deposition at the cathode surface, by passing an external current through the electrolytic cell and using an insoluble anode. During the process, oxygen bubbles are generated at the anode ... En savoir plus
This tutorial uses a simple 1D model of a silicon solar cell to illustrate the basic steps to set up and perform a device physics simulation with the Semiconductor Module. A user-defined expression is used for the photo-generation rate and the result shows typical I–V and P–V curves of ... En savoir plus
In the semiconductor industry, rapid thermal annealing (RTA) is a semiconductor process step used for the activation of dopants and the interfacial reaction of metal contacts. In principle, the operation involves rapid heating of a wafer from ambient to approximately 1000–1500 K. As soon ... En savoir plus
This model solves the Testing Electromagnetic Analysis Methods (TEAM) problem 7, “Asymmetrical Conductor with a Hole”—a benchmark problem concerning the calculation of eddy currents and magnetic fields produced when an aluminum conductor is placed asymmetrically above a multi-turn coil ...

In this set of verification models and associated documentation, the accuracy of electromagnetic force calculations is investigated. Using various techniques, the total force and torque on a rigid body is determined and compared to analytical models. Using fillets, advanced meshing and ... En savoir plus
This model presents two examples of topology optimization of the magnetic circuit of a loudspeaker driver. A first optimization is used to find the design of a nonlinear iron pole piece and top plate that maximize the BL factor at the resting position (small displacements), while ... En savoir plus
When high-fidelity measurement microphones are calibrated, a pressure reciprocity calibration method is used. During calibration, two microphones are connected at each end of a closed cylindrical cavity. For the calibration procedure, it is important to understand the acoustic field ... En savoir plus
This model studies the natural frequencies of a pre-tensioned string using the 2D Wire interface. This is an example of “stress stiffening”; in fact the transverse stiffness of wire elements is directly proportional to the tensile force. Strings made of piano wire have an extremely high ...

This is an example of a model of an induction motor in which eddy currents are induced in the rotor by time-harmonic currents in the stator windings and the rotor's rotation. Induced currents in the rotor interact with the magnetic field that is produced by the coils to generate the ... En savoir plus
This model demonstrates how to couple the Semiconductor interface to the Heat Transfer in Solids interface. A thermal analysis is performed on the existing bipolar transistor model in the case when the device is operated in the active-forward configuration. The Semiconductor interface ... En savoir plus
