The model shows how to calibrate the probability distribution of the Young's modulus and Poisson ratio based on a tensile test. The test measures the tensile force and the radial displacement for different values of the prescribed displacement. The model is based on synthetic data ... En savoir plus
A planar dielectric slab waveguide demonstrates the principles behind any kind of dielectric waveguide such as a ridge waveguide or a step-index fiber. This model solves for the effective index and fields of a dielectric slab waveguide and compares the solution to analytic results. En savoir plus
A distributed Bragg reflector (DBR) is a periodic structure formed from alternating dielectric layers that can be used to achieve nearly total reflection within a range of frequencies, with minimal losses. In this tutorial a Bragg reflector is modeled with a central wavelength of 550[nm] ... 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
Computing molecular flows in arbitrary geometries produces complex integral equations that are very difficult to compute analytically. Analytic solutions are, therefore, only available for simple geometries. One of the earliest problems solved was that of gas flow through tubes of ... En savoir plus
This verification model of nonisothermal laminar flow through a circular tube compares the heat transfer coefficient obtained from simulation with theoretical values based on Nusselt number correlation functions that can be found in the literature. En savoir plus
This example studies heat transfer in a composite two-dimensional structure. Four materials with distinct thermal conductivities k compose the structure. The top and bottom boundaries are facing environments respectively at 0°C and 20°C. The temperature distribution and the heat flux ... En savoir plus
This tutorial demonstrates how to model a gyroscope based on the birdbath resonator gyroscope (BRG) design. The BRG is a type of Coriolis vibratory gyroscope (CVG) invented at the University of Michigan as a navigation-grade gyroscope in the mm-scale. This tutorial shows how the ... En savoir plus
This example shows the behavior of the coupled damage-plasticity material model for concrete when subjected to different loading conditions. En savoir plus
In nuclear fusion reactors, the conducting fluid, such as the fusion plasma and the liquid metal in the reactor blanket, will interact with the background magnetic field. This phenomenon is referred to as magnetohydrodynamics (MHD). The electromagnetic field and fluid flow are fully ... En savoir plus
