The double barrier structure is of interest because of its application in semiconductor devices such as resonant-tunneling diodes. This verification example demonstrates the Schrödinger Equation interface to set up a simple 1D GaAs/AlGaAs double barrier structure to analyze the ... En savoir plus
In this model, two flat end mirrors are placed at a distance and a spherical lens is inserted in the middle of the cavity. A ray is released from a point inside the cavity. Then the ray is traced for a predefined time period that is sufficiently long. Ray tracing continues until the ... En savoir plus
Electroless deposition or plating is a non-galvanic plating method that does not require any external electrical power. This technique is typically used for electroless plating of nickel, silver, gold and copper. In electroless deposition, partial oxidation and reduction reactions ... En savoir plus
This example studies the stationary state of free convection in a cavity filled with air and bounded by two vertical plates. To generate the buoyancy flow, the plates are heated at different temperatures, set in a range to keep the flow laminar. En savoir plus
This tutorial demonstrates a structural analysis of a simple telescope. The deformation of the telescope structure under gravity is examined and the effect on image quality is demonstrated. En savoir plus
Atmospheric corrosion occurs when metallic structures are exposed to humid air forming a thin electrolyte film in the range of up to a few hundred micrometers. The model presented here accounts for charge transport as well mass transport involving 10 species and 6 homogeneous ... En savoir plus
This example demonstrates how to use the Uncertainty Quantification Module by running a series of uncertainty quantification studies for a steel bracket. This type of bracket can be used to install an actuator that is mounted on a pin placed between the two holes in the bracket arms. ... En savoir plus
A 2D model of a steel bar is used to simulate oil quenching from an austenitic state. Both diffusive and displacive phase transformations are used, and the phase composition is computed in the radial direction of the bar. En savoir plus
This model simulates Gaussian to Laguerre Gaussian beam shaping with the Beam Envelopes interface, the unidirectional wave formulation. The input beam is a focusing Gaussian beam with a topological spiral phase. It is known that this phase mask converts a Gaussian beam to a donut ... En savoir plus
This model shows how to create dispersion diagrams from simulation results by extending the tutorial Thin-Film BAW Composite Resonator. The dispersion curve can be plotted against both real and imaginary values of the wave number, corresponding to the propagating modes and evanescent ... En savoir plus
