The four-point bending test is a conventional test method used to test the mechanical properties of materials subjected to bending. It is a reliability test used for semiconductor packaging and assembly. This model demonstrates the stress analysis of an IGBT module subjected to a four ... Read More
The Drift Diffusion interface solves a pair of reaction/advection/diffusion equations, one for the electron density and the other for the mean electron energy. This tutorial example computes the electron number density and mean electron energy in a drift tube. Electrons are released due ... Read More
This model demonstrates how to use the Interior Contact feature to model the contact pressure at a bolted joint connecting two copper busbars. The AC current flowing through the assembly is induced to flow close to the outside boundaries of the conductors, but the contact resistance is ... Read More
The copper current collector on negative graphite electrodes in lithium-ion batteries have been seen to dissolve at over discharge. This can be a safety concern as the dissolution damages the current collector irreversibly and dissolved copper ions can redeposit and form dendrites. ... Read More
This example uses asymptotic techniques to study the radar cross-section (RCS) response of a conductive sphere. The selected physics interface transforms the incident plane-wave field on the boundaries to the far-field using the Stratton–Chu formula. The computed results are compared to ... Read More
Breaker and disconnector devices are widely used in AC substations in power systems.In this model, the Electrostatics Interface is used to simulate the electric potential and electric field in a 110kV 3-phase high-voltage switchgear operating at 50 Hz. A surrogate model is also trained ... Read More
This is an example of a model of an induction motor in which the eddy currents are induced in the rotor by the time harmonic currents on the stator windings and the rotation of the rotor. In this example, we analyze the induction motor in 2D using the transient solver in the Rotating ... Read More
The study explores charge transport dynamics in polyethylene, a common solid dielectric insulation material. It employs a bipolar charge transport model to calculate the densities of electrons, holes, and their trapped counterparts. The simulation's outcomes for discharge current and ... Read More
This model illustrates the process of evaluating the radar cross section (RCS) of a metallic sphere through the utilization of the boundary element method (BEM). By taking advantage of a vertical symmetry plane that is parallel to the polarization of an incident background field, the ... Read More
Lithium iron phosphate (LFP) is a common positive electrode material in lithium-ion batteries. Specific for the LFP electrode material is that its equilibrium (open circuit) potential, when defined as a function of the lithiation state, features a large flat plateau with a more or less ... Read More
