In this model a Knowles ED23146 receiver (miniature loudspeaker) is connected to a test set-up consisting of a 50 mm (1 mm diameter) earmold tube and a so-called 0.4-cc coupler. The receiver is modeled using a lumped spice network and connected to the finite element domain at the tube ... 詳細を見る
Optical lenses of millimeter size cannot easily be analyzed with the Electromagnetic Waves, Frequency Domain interface on standard workstations due to the large number of finite element mesh elements required. This model explains how the Electromagnetic Waves, Beam Envelopes interface ... 詳細を見る
This model demonstrates the switching capability of a liquid crystal (LC) display cell in In-Plane Switching (IPS) configuration. The Oseen-Frank model is used to solve for the LC director (optical axis) distribution when a static electric field is applied. A Weak Form PDE interface is ... 詳細を見る
This example illustrates the modeling of vibration and noise in a 5-speed synchromesh gearbox of a manual transmission vehicle. A transient multibody analysis is performed to compute the gearbox vibration for the specified engine speed and external load. The normal acceleration of the ... 詳細を見る
When a droplet is placed on a substrate on which surface acoustic waves (SAWs) are traveling, the energy of the SAWs is transferred into the droplet to form an acoustic field. The transferred energy is attenuated and generates a streaming flow. This type of streaming enables contactless ... 詳細を見る
The tonpilz (sound mushroom) piezoelectric transducer is a transducer for relatively low frequency, high power sound emission. The transducer consists of piezoceramic rings stacked between massive ends and pre-stressed by a central bolt. The tail and head mass lower the resonance ... 詳細を見る
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 ... 詳細を見る
In this model, a full transient analysis of a loudspeaker driver is performed, which allow the modeling of nonlinear effects. It extends the linear frequency domain analysis done in the Loudspeaker Driver tutorial model. The analysis accounts for nonlinear behavior of the soft iron in ... 詳細を見る
This tutorial studies tissue heating induced by high-intensity focused ultrasound (HIFU). The nonlinear propagation of the HIFU signal is modeled using the Nonlinear Pressure Acoustics, Time Explicit physics interface. In this example, the source amplitude is sufficient to generate ... 詳細を見る
This example model simulates the long-path echo of trumpet sounds reflected from a building 500 m away. The echo can only be heard at night because of the acoustic ray refraction in the atmosphere with different temperature profiles. The model is solved using the ray tracing in the ... 詳細を見る
