In this example, a heat-conduction problem with phase change in a porous material is solved, and the results are compared with the analytical solution, also known as the Lunardini solution. This is the first benchmark case from the InterFrost project, which was initiated to compare ... En savoir plus
In this tutorial you will learn how to use selections when creating the parametric geometry for the analysis of a steam reformer, and set up the selections needed for the physics definitions. The multiphysics analysis of the steam reformer is described in the model Steam Reformer found ... En savoir plus
This model demonstrates how to use the Free Shape Shell feature to increase the stiffness of a shell by deforming its shape. En savoir plus
This example demonstrates how to optimize the thickness of a microelectromechanical systems (MEMS) mirror coating material for maximum reflectivity. To reduce the simulation time, a Layered Impedance Boundary Condition is used to model the thin coating material on top of the metallic ... En savoir plus
While transient analyses are useful for time domain reflectometry (TDR) to handle signal integrity (SI) problems, many RF and microwave examples are addressed using frequency domain simulations generating S-parameters. However, from the frequency domain data it is difficult to identify ... En savoir plus
Lamb wave resonators are useful components for many radio-frequency applications. This tutorial shows how you model an aluminum nitride Lamb wave resonator and perform eigenfrequency and frequency-response analyses to characterize the device. En savoir plus
This model computes the trajectory of an ion in a uniform magnetic field using the Newtonian, Lagrangian and Hamiltonian formulations available in the Mathematical Particle Tracing interface. En savoir plus
The model simulates atmospheric corrosion of a galvanic couple, comprising of an Al-Co-Ce metallic coating and an aluminum alloy, which is in contact with electrolyte film of 100 micrometer thickness. The corrosion inhibitors are released from the metallic coating and are transported ... En savoir plus
In mode analysis it is usually the primary goal to find a propagation constant. This quantity is often, but not always, real valued; if the analysis involves some lossy part, such as a nonzero conductivity or an open boundary, the eigenvalue is complex. In such situations, the real and ... En savoir plus
One way to generate circular polarization from a microstrip patch antenna is to truncate the patch radiator. This model is tuned around the GPS frequency range. The axial ratios are calculated to show the degree of circular polarization. En savoir plus
