Dieses Modell ist als erste Einführung in die Simulationen von Strömungen und konjugiertem Wärmetransport gedacht. Es zeigt Ihnen, wie Sie einen Luftraum um ein Gerät zeichnen, um die konvektive Kühlung in diesem Raum zu modellieren, einen Gesamtwärmestrom an einer Grenze mithilfe der ... Mehr lesen
This benchmark model computes the total force acting on a vibrating disc in the frequency and time domains and compares both results with expressions derived analytically. When the vibration amplitude is small enough that the system is linear the frequency and time domain results agree ... Mehr lesen
A Fresnel lens can be constructed from a plano-convex lens as a way to reduce the thickness. This model models the collimation property of a Fresnel lens and demonstrates the geometry operation of making a Fresnel lens from a plano-convex lens. Mehr lesen
A Branch Line Coupler (Quadrature 90° Hybrid) is a four-port network device with a 90° phase difference between two coupled ports. The device can be used for a single antenna Transmitter/Receiver system or an I/Q signal splitter/combiner. The objective of this model is to compute the S ... Mehr lesen
This tutorial model demonstrates how to compute the impedance of a capacitively coupled plasma. The Time Periodic study computes the time periodic solution of the plasma. Subsequently, the solution is transformed to the time domain, after which the fast Fourier transform (FFT) solver is ... Mehr lesen
This tutorial model demonstrates how to estimate the material parameters of a combined hardening elastoplastic material model given cyclic shear data. Mehr lesen
The electrochemical cell shown in this model can be regarded as a unit cell of a larger wire-mesh electrode that is common in many industrial processes. One of the most important aspects in the design of electrochemical cells is the current density distributions in the electrolyte and ... Mehr lesen
This example demonstrates how to set up a spatially varying dielectric distribution. Here, a convex lens shape is defined via a known deformation of a rectangular domain. The dielectric distribution is defined on the undeformed, original rectangular domain and is mapped onto the deformed ... Mehr lesen
This model incorporates the transport and electrolytic reaction in the treatment of tumor tissue. Oxygen evolution at the anode produces protons, which lowers the pH, while chlorine production also leads to lowered pH through the hydrolysis of chlorine. One effect of a low pH is the ... Mehr lesen
Small heating circuits find use in many applications. For example, in manufacturing processes, they heat up reactive fluids. The device in this tutorial consists of an electrically resistive layer deposited on a glass plate. The layer results in Joule heating when a voltage is applied to ... Mehr lesen
