An important and interesting phenomenon with supersonic flows are expansion fans, which take place when the flow encounters a convex or expansion corner. The direction of the flow changes smoothly across the fan, while the Mach number increases. This 2D example models an expansion fan ... En savoir plus
A cable is a structural member which has stiffness only in its tangential direction, but virtually no bending stiffness. When supported only at its two ends it deflects under gravitational load forming a curve known as catenary. This example shows how to model components such as cables, ... En savoir plus
In this example, triaxial and oedometer tests are simulated using the Hardening Soil material model. Both tests exhibit a hyperbolic stress–strain relationship. For the triaxial test, it is confirmed that the axial stress approaches the analytical failure stress asymptotically. In the ... En savoir plus

A plane-wave mode feeds an axisymmetric horn radiating from an infinite baffle toward an open half space. The radius of the waveguide attached to the horn throat is assumed to be fixed, as well as the depth of the horn and the size of the horn mouth attached to the baffle. By varying the ...

The transmission speed of optical waveguides is superior to microwave waveguides because optical devices have a much higher operating frequency than microwaves, enabling a far higher bandwidth. Single-mode step-index fibers are used for long-haul (even transoceanic) communication, ... En savoir plus
This model is intended as a first introduction to simulations of fluid flow and conjugate heat transfer. It shows you how to: Draw an air box around a device in order to model convective cooling in this box, set a total heat flux on a boundary using automatic area computation, and ... En savoir plus
Feeding antennas with proper signals can be difficult. The signal is often described as a voltage, and voltages are not well defined in electromagnetic wave formulations. There are several tricks to model voltage generators in such situations, and one is the magnetic frill. This model ... En savoir plus
The elastoacoustic effect is a change in the speed of elastic waves that propagate in a structure undergoing static elastic deformations. The effect is used in many ultrasonic techniques for nondestructive testing of prestressed states within structures. This example studies the ... En savoir plus
