A Mach-Zehnder modulator is used for controlling the amplitude of an optical wave. The input waveguide is split up into two waveguide interferometer arms. If a voltage is applied across one of the arms, a phase shift is induced for the wave passing through that arm. When the two arms are ... Per saperne di più
This is a benchmark model for a plane stress problem. The accuracy of the computed stress concentration is evaluated, and a mesh convergence study is performed for different element types. Per saperne di più
This example demonstrates the use of the Solid-Beam Connection multiphysics coupling to create transitions between the Solid Mechanics and Beam interfaces. Two different connection types are discussed, and a comparison of the stress distributions at the transition is made. Per saperne di più
