This model illustrates the effect of oxygen and hydrogen formation and recombination on the performance and self-discharge of an electrochemical capacitor with a water-based electrolyte. A load cycle consisting of mixed constant current pulses and rest periods at an open circuit is ... En savoir plus
In this example, the properties of an engineeredmaterial are modeled by a spatially varying dielectric distribution. Specifically, a convex lens shape is defined via a known deformation of a rectangular domain. The dielectric distribution is defined on the undeformed, original ... En savoir plus
This benchmark studies the nonlinear deformation of a spherical cap subjected to point load at center using 2D axisymmetric Solid Mechanics and Shell interfaces. The results from the Shell interface are compared with Solid Mechanics interface as well as with analytical results given in ... En savoir plus
Topology optimization for low volume fractions in 3D follows the same methodology as in 2D for medium volume fractions. The only difference is the need for iterative solvers. This model demonstrates topology optimization of a drone for a volume fraction of 12.5 %, while considering two ... En savoir plus
This model simulates the discharge of a Nickel-Metal Hydride (NiMH) battery using the Battery with Binary Electrolyte interface. The geometry is in one dimension and the model is isothermal. The model serves as an introduction to NiMH modeling, and can be further extended to include ... En savoir plus
This model simulates an electrodeless lamp with argon/mercury chemistry. The low excitation threshold for mercury atoms means that even though the mercury is present in small concentrations, its behavior dominates. There is strong UV emission from the plasma at 185 nm and 253 nm. The UV ... 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
When the Vdara hotel first opened in Las Vegas, visitors relaxing by the pool would experience intense periods of heat at certain times of the day, at certain times of the year. This intense heat was caused by the reflection of solar radiation from the curved, reflective surface on the ... En savoir plus
Shape optimization with respect to fatigue properties is not supported, but fatigue properties are well correlated with the maximum stress. The model demonstrates how optimization with respect to a p-norm of the von Mises stress can be used to improve fatigue properties without ... En savoir plus
This model demonstrates how to define Earth properties that are spatially varying on the planet. A satellite in orbit experiences solar, albedo, and planetary infrared (IR) loads, where albedo and planetary IR can vary with latitude and longitude. In this example, these inputs are read ...
