An ion-sensitive field-effect transistor (ISFET) is constructed by replacing the gate contact of a MOSFET with an electrolyte of interest. The concentration of a specific ionic species in the electrolyte can be determined by measuring the change in the gate voltage due to the interaction ... Mehr lesen
This model simulates an electrodeless lamp with argon/mercury chemistry. The low excitation threshold for mercury atoms means that even though the mercury is present in small concentrations, its behavior dominates. There is strong UV emission from the plasma at 185 nm and 253 nm. The UV ... Mehr lesen
The electron energy distribution function (EEDF) plays an important role in the overall behavior of discharges. In this example, the formation period of an Argon plasma is studied with special attention paid to the EEDF. The plasma is created within a 4 cm gap by a DC source voltage of 1 ... Mehr lesen
Aldicarb is a commercial pesticide, used on a variety of crops, including cotton, fruits, potatoes, and beans. This arises in the possibility that the general population may be exposed to aldicarb through the ingestion of contaminated water and foods. This example looks at the ... Mehr lesen
High-performance liquid chromatography (HPLC) is a common method of separating, identifying, and quantifying each chemical compound in a mixture. HPLC is found in the pharmaceutical, biotech, and food industries. The Liquid Chromatography app simulates the separation of two species ... Mehr lesen
This tutorial shows how to set up a ray release based on the incident electric field at a boundary. First the Electomagnetic Waves, Frequency Domain interface is used to solve for the electric field of a plane wave. Then rays are released with initial intensity and polarization matching ...

This tutorial uses a simple 1D model of a silicon solar cell to illustrate the basic steps to set up and perform a device physics simulation with the Semiconductor Module. A user-defined expression is used for the photo-generation rate and the result shows typical I–V and P–V curves of ... Mehr lesen
Dieses Beispiel simuliert die turbulente Strömung um einen Sportwagen, der mit einer Geschwindigkeit von 180 km/h fährt, mithilfe von Large-Eddy-Simulationen (LES). Mehr lesen
Induction pumps are used in high temperature cooling systems. The principle of operation is equivalent to a linear three phase induction motor. The lack of moving parts and the pumped liquid being kept in a hermetically closed system are clear advantages. This model shows how to simulate ... Mehr lesen
Predicting the noise radiation from a dynamic system gives designers insight into the behavior of moving mechanisms early in the design process. For example, consider a gearbox in which the change in the gear mesh stiffness causes vibrations. These vibrations are transmitted to the ... Mehr lesen
