An eigenfrequency study is used to find the resonance frequency and threshold gain for an oxide-confined, GaAs-based, vertical-cavity surface-emitting laser (VCSEL). The simulations are performed in two steps. A regular eigenfrequency analysis is first performed, to find good initial ... 詳細を見る
This example reproduces parts of the study of Ref. 1 on the thermal contact resistance at the interface between a heat sink and an electronic package. Eight cooling fins equip the cylindrical heat sink and contact is made at the radial boundaries of the package. The efficiency of the ... 詳細を見る
This example exemplifies how to model thermal ablation by taking into account material removal. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Modeling Thermal Ablation for Material Removal". 詳細を見る
This model simulates a GaN based light emitting diode. The emission intensity, spectrum, and quantum efficiency are calculated as a function of the driving current. Direct radiative recombination across the band gap is modeled, as well as non-radiative Auger and trap-assisted ... 詳細を見る
This model simulates a plasma at medium pressure (2 torr) where the plasma is still not in local thermodynamic equilibrium. At low pressures the two temperatures are decoupled but as the pressure increases the temperatures tend towards the same limit. 詳細を見る
This model simulates an LED that emits in the infrared part of the electromagnetic spectrum. The device structure is made up of a single p-n junction formed by a layer of p-type doping near the top surface of an otherwise n-type wafer. This kind of device geometry is simple and cheap to ... 詳細を見る
When anodizing aluminum, the surface is electrochemically altered to form an abrasive and corrosion-resistive Al2O3 film. The electrode kinetics during the process are only marginally affected as the oxide layer grows, so a stationary analysis of the current distribution is sufficient to ... 詳細を見る
Multilateral wells—those with multiple legs that branch off from a single well—can produce oil efficiently because the legs can tap multiple productive zones and navigate around impermeable ones. Unfortunately, drilling engineers must often mechanically stabilize multilateral wells with ... 詳細を見る
Using a Fluid-Solid Interaction multiphysics interface, the behavior of a spring-loaded ball check valve is studied under varying functional and reverse flow. The fluid force acting on the ball opens the valve at the opening pressure. In the case of a reversed pressure, the ball comes ... 詳細を見る
The first part of the application computes the modes for a straight step index fiber made of silica glass. In the second part, a step index fiber bend with a 3 mm radius of curvature is analyzed with respect to propagating modes and radiation loss. It is shown how to find the power ... 詳細を見る
