The suspension of a loudspeaker is designed to keep the membrane in place and avoid any rocking movement of the voice coil. At low frequencies, where the displacement of the membrane is significant, the stiffness of the suspension varies along the movement of the voice coil. This ... En savoir plus
This tutorial model solves for a hydrogen plasma created in a microwave cavity. The model computes the fluid flow and gas heating self-consistently. En savoir plus
In this set of eight tutorial models and associated documentation, you can investigate the resistive, capacitive, inductive, and thermal properties of a standard three-core lead-sheathed XLPE HVAC submarine cable with twisted magnetic armor (500 mm2, 220 kV). The series includes a 2D, 2D ... En savoir plus
This app demonstrates the following: Geometry parts and parameterized geometries Sending an email with a report when the computation is finished User-defined email server settings which is useful when running compiled standalone applications Options for setting different mesh sizes ...

This model presents a 2D axisymmetric dipolar microwave plasma source sustained through resonant heating of the electrons. This is known as electron cyclotron resonance (ECR), which occurs when a suitable high magnetic flux density is present along with the microwaves. This is an ... En savoir plus
A tweeter is a high frequency driver used in loudspeaker systems. An ideal tweeter will produce a constant sound pressure level at a given distance in front of the driver independently of frequency, that is, a flat response. Ideally the tweeter will also, to a certain degree, maintain ... En savoir plus
Fatigue testing of nonlinear materials with creep mechanism is a time-consuming process. In accelerated life testing the experiment time is greatly reduced by subjecting the material to testing conditions in excess of the operating one. In the model an aggressive thermal load cycle is ... En savoir plus
The following model examines unsteady, incompressible flow past a long cylinder placed in a channel at right angle to the oncoming fluid. The cylinder is offset somewhat from the center of the flow to make the steady-state symmetrical flow unstable. The simulation time necessary for a ... En savoir plus
This example demonstrates how you can use modeling to investigate the performance of different hydrodynamic journal bearings. The model uses the Hydrodynamic Bearing interface, which solves the Reynolds equation to compute the pressure developed in a thin fluid film for four different ... En savoir plus
Composite laminates are synthetic structures and there is always a possibility to optimize the design in terms of the number of layers, the material of each layer, the thickness of each layer, and the stacking sequence for the specified loading conditions. Designers need to know how safe ... En savoir plus
