Combinations of optical devices such as polarizers and wave retarders can be used to control the intensity and polarization of transmitted radiation. In this tutorial, two linear polarizers with orthogonal transmission axes are used to reduce the intensity of a ray to zero. Then the ... En savoir plus
This example illustrates the modeling of vibration and noise in a 5-speed synchromesh gearbox of a manual transmission vehicle. A transient multibody analysis is performed to compute the gearbox vibration for the specified engine speed and external load. The normal acceleration of the ... En savoir plus
Drying of porous media is an important process in the food and paper industry among others. Many physical effects must be considered: fluid flow, heat transfer with phase change, and transport of participating liquids and gases. All of these effects are strongly coupled, and predefined ...

In this study, the compressible turbulent flow through a supersonic ejector is modeled using the High Mach Number Flow interface in the CFD Module. Ejectors are simple mechanical components used for a wide range of applications, including industrial refrigeration, vacuum generation, gas ... En savoir plus
This is the model of an occluded ear canal simulator (a generic 711 coupler). Besides certain details the geometry corresponds to the Brüel & Kjær Ear Simulator Type 4157. The real life couplers are used for simulating the acoustics of a standardized human ear canal and can be used ... En savoir plus
This model shows how to implement an anisotropic, incompressible, hyperelastic material for modeling soft collagenous tissue in arterial walls. The hyperelastic material model implemented is based on the articles: Holzapfel, G. A., Gasser, T. C., & Ogden, R. W. (2000), A new ... En savoir plus
This model shows how to model the avalanche breakdown due to the impact ionization in a Silicon Carbide diode. The current-voltage (I-V) characteristics of the device are presented as well as the electric field distribution plot. Furthermore, the carrier generation term has been computed ... En savoir plus
An Einzel lens is an electrostatic device used for focusing charged particle beams. It may be found in cathode ray tubes, ion beam and electron beam experiments, and ion propulsion systems. This particular model consists of three axially aligned cylinders. The outer cylinders are ... En savoir plus
This example shows how to compute the critical buckling load in the presence of dead loads. A truss tower is supported by pretensioned guys. The pretension load and gravity on the truss are considered as dead loads, while the vertical load applied at the top of the tower is considered ... En savoir plus
This example shows how to model a FinFET in 3D. The I-V characteristics of the device are simulated. First, the gate voltage is swept to obtain the drain current versus gate voltage plot. Then, the drain current versus drain voltage characteristics are computed for fixed gate voltages. En savoir plus
