This model computes the specific acoustic radiation impedance of a very small circular vent in a flanged configuration. The model includes thermoviscous losses. The radiation impedance is fitted using a simple RL circuit which gives a simple lumped representation. The results are used ... En savoir plus
This model uses the Semiconductor and RF modules to describe a photoconductive antenna (PCA). A laser pulse is applied on the surface of undoped LT-GaAs to generate electron-hole-pairs, which move under the influence of an external E-field creating a transient electric current pulse. ...

Inside of a combustion chamber, the gas mix behaves as a non-gray medium. Such media require a lot of data and computational resources to get results across the whole spectrum. The Weighted Sum of Gray Gases Model (WSGG) proposes an approach to model the non-gray gas mix as a sum of ... En savoir plus
The present model demonstrates diffusion-controlled electrodeposition of copper on microstructured band electrode arrays (MEA). Mass transport by Fickian diffusion of copper ions is solved using the Transport of Diluted Species interface. Dendrite formation as a consequence of diffusion ... En savoir plus
The model of 1D Dielectric Barrier Discharge (DBD) has been recomputed with the three different kinds of electron energy distribution functions (EEDFs): The Maxwellian function The Druyvesteyn function The computed EEDF based on the Boltzmann Equation, Two-Term Approximation ... En savoir plus
In this model a plane wave with circular polarization is reflected off an interface between air and glass. The model demonstrates three different ways of defining this problem. The first part shows how to define user-defined port mode fields. The second part uses the predefined circular ... En savoir plus
The liquid electrolyte in lithium-ion batteries (LIBs) typically consists of a lithium salt, such as LiPF6, dissolved in one or several solvents. Commercial LIBs commonly employ a mix of multiple hydrocarbon-based solvents along with additional additives. In an electrolyte consisting of ... En savoir plus
Bearing clearances should be kept minimum to avoid non-synchronous vibration of a rotor. However, a tight clearance reduces the durability of the bearing. This example illustrates modeling of the vibration induced by nonlinear contact for different radial clearances. It is shown that ... En savoir plus
This tutorial demonstrates how to model the band-to-band tunneling across a p–n junction. The tunneling effect is imitated by defining the User-Defined Recombination domain feature which makes the electrons disappear from the conduction band on the n-side and holes disappear from the ...

The problem of a plane wave scattering off a cylinder-shaped object suggests the use of the 2D axisymmetric formulation. This can save computation time and reduce the memory usage compared to the model in 3D space. This example demonstrates the use of the built-in plane wave expansion ... En savoir plus
