This example shows how to perform a topology optimization with several load and constraint cases. The density feature for topology optimization is used together with a parametric sweep where each optimized solution is used as input for a further improved optimization. The final ... En savoir plus
Feeding a waveguide from a coaxial cable is a straightforward way to achieve electromagnetic waves inside a waveguide. Due to its small size and circular shape, the cable contributes significantly to the overall size of the problem. It is therefore necessary to keep the cable as short as ... En savoir plus
In this example, wrinkling is studied in a cylindrical membrane of nonuniform thickness under axial and pressure loading. The membrane is modeled as an incompressible Mooney–Rivlin material. During axial stretching, certain portions of the membrane undergo wrinkling; however, the ... En savoir plus
This tutorial model is kindly provided by Riccardo Vietri, James Ransley and Andrew Spann at Veryst Engineering, LLC. Piezoelectric micropumps are frequently used in medical applications because of their ability to precisely control the metering of very small volumes of fluids or gases. ... En savoir plus
This is a benchmark model for flexible multibody dynamics. This model simulates the dynamic behavior of a planar four-bar mechanism when one of the joints has a defect. The out-of-plane motion in the mechanism, caused by the defect in the joint, is compared with the results from the ... En savoir plus
Light pipes are structures that can be used to transport light between different locations. In general, they can be divided into two major groups: tubes lined with a reflective coating and transparent solids that contain light via total internal reflection. In this tutorial, light is ...

These models use the Discrete Ordinates method (DOM) and P1 approximation to solve a 3D radiative transfer problem in an emitting, absorbing, and linear-anisotropic scattering finite cylindrical medium. Using the S6 quadrature of DOM leads to accurate results, which are needed in ... En savoir plus
This model shows how to use the Free Shape Boundary feature to increase the stiffness of a wrench without increasing its mass. En savoir plus
Extending the Tuning Fork model, this example shows how to set up an Optimization Study to determine the prong length at which the fork vibrates at the standard concert pitch, 440 Hz. En savoir plus
This model demonstrates the use of boundary element method in the Electromagnetic Waves, Boundary Element interface to model an optical Yagi-Uda antenna. The antenna is driven by an electrical point dipole, which is implemented through the background field. The field distribution around ... En savoir plus
