The incompressible boundary layer on a flat plate in the absence of a pressure gradient is usually referred to as the Blasius boundary layer. The steady, laminar boundary layer developing downstream of the leading edge eventually becomes unstable to Tollmien-Schlichting waves and finally ... 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
Applying an electric field across a suspension of immiscible liquids may stimulate droplets of the same phase to coalesce. The method known as electrocoalescence has important applications, for instance, in the separation of oil from water. To model electrocoalescence, you need to solve ... En savoir plus
This example is inspired by a classic bridge type called a Pratt truss bridge. You can identify a Pratt truss by its diagonal members, which (except for the outermost ones) all slant down in span-wise direction towards the bridge’s center. All the diagonal members are subject to tension ... En savoir plus
In this example, the eigenmodes of a structural damper are computed. In the damper, most of the deformation is controlled by the viscoelastic domains, which have strongly frequency-dependent stiffness and damping properties. This leads to a nonlinear eigenfrequency problem, which can be ... En savoir plus
This example describes how to simulate the flow of a thin film of fluid in the gap between two rectangular plates, one of them with a porous facing, when the fluid is squeezed as a consequence of the relative motion between the plates. The model accounts for the ingress and egress of ... En savoir plus
DC glow discharges in the low-pressure regime have long been used for gas lasers and fluorescent lamps. DC discharges are attractive to study because the solution is time independent. The 1D and 2D models show how to use the DC Discharge interface to set up an analysis of a positive ... En savoir plus
A square airbag made of a hyperelastic, compressible neo-Hookean material is inflated using pressurized air. Compressive stresses trigger wrinkling in some regions of the thin airbag. In this example, the wrinkling behavior is modeled using tension field theory, which gives a correct ... En savoir plus
This tutorial demonstrates the use of the density-gradient formulation to include the effect of quantum confinement in the device physics simulation of a silicon inversion layer. This formulation requires only a moderate increase of computational resources as compared to the conventional ... En savoir plus
In this example, which serves as a tutorial for contact analyses, the insertion of a snap hook in its groove is studied. A linear elastic material model is used. En savoir plus
