This tutorial introduces the use of topology optimization in acoustics. The goal of the optimization is to find the optimal material distribution (solid or air) in a given design domain, here the ceiling of a 2D room, that minimizes the average sound pressure level in an objective ... Mehr lesen
An Electromagnetic Band Gap (EBG) structure can be used to increase the isolation between antennas close to each other. The decoupling effect is not only a function of frequency but also polarization and coupling-plane configuration. When designing an EBG structure, one needs to make ... Mehr lesen
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 ... Mehr lesen
This model computes the lightning-induced voltage on an overhead line positioned above a lossy ground. It includes parameters like the inclination angle of lightning channels and soil conductivity, enabling straightforward analysis of their impacts. The calculated induced voltage aligns ... Mehr lesen
This tutorial model shows how to import data from an ODB++® archive to generate a geometry of a printed circuit board (PCB). Follow the instructions to learn how to remove small details from the geometry, create a mesh, and use automatically generated selections to define physics and ... Mehr lesen
Surface chemistry is often an overlooked aspect of reacting flow modeling. This tutorial model shows how surface reactions and species can be added to study processes like chemical vapor deposition (CVD). The tutorial then models silicon growth on a wafer. Initially, the example uses a ... Mehr lesen
A spherical water-rich load (potato) is placed on the rotating glass tray of a microwave oven some distance from the center of rotation. 1 kW of 2.45 GHz microwave power is applied via a waveguide feed. The plate rotates at 9 degrees per second. The heat transfer model involves the ... Mehr lesen
Deposition of metallic lithium on the negative electrode in preference to lithium intercalation is known to be a capacity loss and safety concern for lithium-ion batteries. Harsh charge conditions such as high currents (fast charging) and/or low temperatures can lead to lithium plating. ... Mehr lesen
Vermeiden Sie wackelnde Fenster und verbessern Sie das Klangerlebnis durch sorgfältige Positionierung der Lautsprecher in Ihrem Raum. In diesem Tutorial wird der tiefe Frequenzgang eines Wohnzimmers für die Tieftöner von zwei Lautsprechern analysiert und die Eigenfrequenzen des Raums ... Mehr lesen
This is a full vibro-electroacoustic simulation of a balanced armature transducer (BAT or also known as a receiver in some industries) which is a high-performance miniature loudspeaker often used in hearing aids and other in-ear audio products such as earbuds. The model is set up and ... Mehr lesen
