This model treats the free convection and heat transfer of a glass of cold water heated to room temperature. Initially, the glass and the water are at 5 °C and are then put on a table in a room at 25 °C. The nonisothermal flow is coupled to heat transfer using the Heat Transfer module. En savoir plus
A signal integrity (SI) analysis gives an overview of the quality of an electrical signal transmitted through electrical circuits, such as high-speed interconnects, cables, and printed circuit boards. The quality of the received signal can be distorted by noise from outside the circuit, ... En savoir plus
In this model, sound created by a vibrating piston radiates through a baffled pipe. The impedance is measured and then used in an impedance boundary condition that replaces the surrounding air domain. This technique can be employed to reduce solution time and memory usage for large ... En savoir plus
Power lines are commonly used as a means of transmitting electrical power across large distances. In this tutorial, towers transmitting high voltage three-phase AC power are modeled, and the resulting electric field is computed. The towers have two shielding lines. The model also ... En savoir plus
Tutorial model of an air-cooled battery energy storage system (BESS). The model includes conjugate heat transfer with turbulent flow, fan curves, internal screens, and grilles. It features several interesting aspects: Fully parameterized geometry, which can be modified for different ... En savoir plus
This model investigates the wave propagation in a photonic crystal that consists of GaAs pillars placed equidistant from each other. The distance between the pillars determines a relationship between the wave number and the frequency of the light, which prevents light of certain ... En savoir plus
This model analyzes the thermal expansion in a MEMS device, such as a microgyroscope, where thermal expansion should be minimized. The device is made from the copper-beryllium alloy UNS C17500 and uses temperature-dependent material properties from the Material Library. The purpose of ... En savoir plus
This model demonstrates how to perform simulations of an absorbing bandstop color filter, based on a hexagonal array of holes in a thin aluminum layer. The structure is hexagonally periodic but this example also shows how to set the model up as rectangularly periodic. En savoir plus
This 2D stationary model computes heat and moisture transport in a wall composed of different hygroscopic materials. A comparison with the Glaser method is given for the temperature and relative humidity solutions. The effect of the use of a vapor barrier is also investigated. En savoir plus
Passive devices can be designed using lumped element features if both the operating frequency of the device and the insertion loss of lumped elements are low. This example simulates two types of lumped element filters that are similar to lumped ports, except that they are strictly ... En savoir plus
