An antenna array is a group of radiating elements. By controlling the phase and magnitude of the input signal assigned to each antenna element and the number of array elements, the radiation pattern can be steered in a desired direction with a preferred level of gain. In this example, a ... En savoir plus
There are multiple ways to excite and terminate transmission lines using different types of port and lumped port features. In this example, transverse electromagnetic (TEM) type ports and a via type lumped port are used to simulate two adjacent microstrip lines. One via end is terminated ... En savoir plus
The electrostatically tunable parallel plate capacitor in this example is a typical component in various MEMS devices for radio frequencies that range between 300 MHz and 300 GHz. You can modify the distance between the two plates, as the applied voltage changes, through a spring ... En savoir plus
This example models an oil reservoir with two horizontal wells. The reservoir contains two phases, water and oil. Oil is recovered by injecting water through the bottom well, so the oil production rate and the water-oil production ratio over time are computed. En savoir plus
In this classical benchmark model, a spherical scatterer is placed in a plane wave background field. When the sphere is modeled as sound hard, the problem has an analytical solution. The model compares the results using the Pressure Acoustics, Boundary Elements interface with the ... En savoir plus
This 3D model example demonstrates the use of the Primary Current Distribution interface for modeling current distributions in electrochemical cells. In primary current distribution, the potential losses due to electrode kinetics and mass transport are assumed to be negligible, and ... En savoir plus
This example demonstrates simulation of a turbulent flow in a geometry with an air filter. Porous material of the filter induces an abrupt pressure drop and drastic increase of turbulence level inside the filter. En savoir plus
A cooling flange in a chemical process is used to cool the process fluid, which flows through the flange. The surrounding air cools the flange via natural convection. In the stationary model, the forced convection to the process fluid is modeled using a constant heat transfer ... En savoir plus
This tutorial shows how to set up a multi-element objective lens. The chosen lens is the Double Gauss described in 'Modern Lens Design (2nd edition)', by W. Smith, 2005, pg 323. The tutorial demonstrates how to create a geometry sequence using the 'Spherical Lens 3D' part found in the ... En savoir plus
Double-pipe heat exchangers, with their typical U-turn shape, are one of the simplest and cheapest type of heat exchangers used in the chemical process industry. This example studies the cooling of hot oil (130°C) by a cool oil (60°C) entering in counter-current. As the oils flow ... En savoir plus
