The model demonstrates the basics of the 3-omega method. The coupled electromagnetic heating problem is solved in a solid sample which is heated by a thin copper strip, deposited on the surface of a sample. Analyzing the frequency dependence of the voltage oscillation amplitude, we ... En savoir plus
Due to the demand for larger power with a smaller size, dual-shaft systems with intershaft bearings are becoming a standard configuration for gas turbine engines. Such systems consist of two coaxial rotors running at different speeds, interlinked through a multi-spool bearing. In this ... En savoir plus
This model shows how to use the scattered field formulation to compute the transmission coefficient for impinging P and S plane elastic waves onto a finite size phononic crystal. The transmission tends to zero in the frequency range corresponding to P- and S-wave band gaps, as ... En savoir plus
Wind turbines are an increasingly popular source of renewable energy. As such, the design, analysis and manufacture of wind turbines are important to the energy industry. The turbine blades are critical components of a wind turbine. When generating electric power through rotation, they ... En savoir plus
In this example, the natural frequencies of a double hat beam are studied. The beam is made of two thin steel plates, joined together by spot welds along the flanges. The Spot Welds feature sets up multiple mesh-independent connections between the shells. En savoir plus
This example is an extension of a model used to study the vibration and noise in a 5-speed synchromesh gearbox in a manual transmission vehicle. In this version of the model, a detailed representation of a roller bearing is used instead of hinge joints with elastic stiffness. First, the ... En savoir plus
This model determines the reflection coefficient of plane acoustic waves, at different frequencies and at different angles of incidence, off a water-sediment interface. The ability of the Poroelasitc Waves interface to model the coupled acoustic and elastic wave in any porous substance ... En savoir plus

Numerical modeling of Lamb waves, which belong to guided waves, is essential for the analysis and design of the structural health monitoring (SHM) systems for long range ultrasonic testing. The design of an SHM system based on guided waves consists of two main parts. In the first place, ... 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 magnetic field is computed. The towers have two shielding lines. En savoir plus
