Prevent shaking windows and enhance the sound experience by careful positioning of the loudspeakers in your room. This tutorial analyzes the low frequency response of a living room to the woofer units of two loudspeakers, and solves for the eigenfrequencies of the room. The room geometry ... En savoir plus
This is a simple yet powerful simulation app for designing a two-dimensional reflective metalens. This metalens consists of a array of glass nanopillars on a metal substrate. Initially, the app determines the optimal grating parameters for a specific wavelength and calculates the ... En savoir plus
This model demonstrates how to perform a hearing aid acoustic feedback response analysis, including both the in-ear hearing aid and the hearing aid cassette. The hearing aid modeled is a ReSound OMNIA™ device from GN Hearing A/S. The hearing aid is tested on a combined pinna and ear ... En savoir plus
Ultrasonic flowmeters determine the velocity of a fluid flowing through a pipe by sending an ultrasonic signal across the flow at a skew angle. When there is no flow, the transmitting time between the transmitter and the receiver is the same for the signals sent in the upstream and ... En savoir plus
Coriolis flowmeters, also known as mass flowmeters or inertial flowmeters, measure the mass flow rate of a fluid traveling through it. It makes use of the fact that the fluid's inertia through an oscillating tube causes the tube to twist in proportion to the mass flow rate. Typically, ... En savoir plus
In this tutorial, a filter system for a diesel engine is modeled, including a soot layer development and oxidization. The build-up of the layer is held in check by both catalytic and non-catalytic reactions, where carbon is oxidized to carbon monoxide and carbon dioxide, which in turn ... En savoir plus
In this example, a heterogeneous NMC (Nickel-Manganese-Cobalt) electrode structure is generated from tomography data using a Model Method. Time-dependent discharge and electrochemical impedance spectroscopy (EIS) simulations are then made on the full 3D geometry. A solid mechanics ... En savoir plus
Knowing the velocity of a moving fluid is important in all cases where the fluid is used to transport material or energy. In the time-of-flight or transit-time method for determining flow velocity, an ultrasonic signal is transmitted across the main flow in a pipe to noninvasively ... En savoir plus
A distributed Bragg reflector (DBR) is a periodic structure formed from alternating dielectric layers that can be used to achieve nearly total reflection within a range of frequencies. The main advantage of DBRs over ordinary metallic mirrors is that DBRs can be engineered to have custom ... En savoir plus
When computing ray intensity in 2D axisymmetric models, the wavefront associated with the propagating ray is treated as a spherical or ellipsoidal wave, instead of a cylindrical wave. This tutorial example illustrates how to set up several important features using the Ray Acoustics ... En savoir plus
