This simple benchmark model computes the potential and carrier concentrations for a one-dimensional p-n junction using both the finite element and finite volume methods. The results are compared with an equivalent device from the book, "Semiconductor Devices: A Simulation Approach," by ... 詳細を見る

This model demonstrates how to compute the volumetric fluence rate in an ultraviolet (UV) reactor. The geometry is the annular fluid region surrounding a cylindrical lamp. The effect of reflection at the reactor walls on the radial fluence rate distribution is considered. 詳細を見る

As integrated circuit (IC) technology advances, with circuits becoming more powerful and compact, it is increasingly important to identify and prevent any cause of circuit failure. One particularly critical factor contributing to circuit failure is electromigration within the ... 詳細を見る

Powder compaction is a key process in powder metallurgy, where it gives the flexibility to produce quality products of complex shapes for sintering. The density of the compact is a key factor to determine the overall quality of the sintered product, as regions with lower density could ... 詳細を見る

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 ... 詳細を見る

This tutorial demonstrates how a lumped model of a MEMS transducer can be derived from its FEM model. It includes an FEM model of a capacitive micromachined ultrasonic transducer (CMUT) and the corresponding lumped model created using the Lumped Mechanical System (LMS) interface. The ... 詳細を見る

These models use the Discrete Ordinates method (DOM) and P1 approximation to solve a 3D radiative transfer problem in an emitting, absorbing, and linear-anisotropic scattering finite cylindrical medium. Using the S6 quadrature of DOM leads to accurate results, which are needed in ... 詳細を見る

The model shows how to calibrate the probability distribution of the Young's modulus and Poisson ratio based on a tensile test. The test measures the tensile force and the radial displacement for different values of the prescribed displacement. The model is based on synthetic data ... 詳細を見る

斜角超音波ユニットは, 金属パイプなどの固体の非破壊検査 (NDT) に使用されます. これらは, 気孔, 小さな亀裂, 融合不足など, 溶接領域内および溶接領域周辺の欠陥を検出するのに特に役立ちます. 斜角 NDT は, 垂直ビーム検査では欠陥を見つけるのが難しい場合によく使用されます. たとえば, 亀裂が垂直で細いため, 反射量が少ないために検出できない場合などです. 斜角 NDT の動作原理は, トランスデューサーによって送信された縦波 (圧縮波) をテストサンプルで屈折した横波 (横波) に変換することにあります. 次に, ... 詳細を見る

The model simulates non-premixed turbulent combustion of syngas (synthesis gas) in a simple round-jet burner. Syngas is a gas mixture, primarily composed of hydrogen, carbon monoxide and carbon dioxide. The name syngas relates to its use in creating synthetic natural gas. In the model, ... 詳細を見る
