Frequency-selective surfaces (FSS) are periodic structures with a bandpass or a bandstop frequency response. This model shows that only signals around the center frequency can pass through the periodic complementary split ring resonator layer. En savoir plus
All integrated circuits (ICs) — especially high-speed devices — produce heat. In today’s dense electronic system layouts, heat sources are many times placed close to heat-sensitive ICs. Designers of printed circuit boards often need to consider the relative placement of heat ... En savoir plus
This model simulates the isotropic compression of naturally structured and artificially structured clays using the Modified Structured Cam-Clay (MSCC) material model. The aim of the example is to reproduce the compression behavior given in a benchmark for four structured clays. En savoir plus
A slope stability analysis is performed and the Factor of Safety of the dam embankment is calculated by using the Shear Strength Reduction Technique. The pore pressure in the soil is computed based on Darcy’s law, and the Mohr–Coulomb constitutive model is used to describe the ... En savoir plus
This example shows how to model a deep excavation. The main application area of this type of modeling is in civil engineering. In this case, the in situ lateral pressure acting on the retaining wall during the soil excavation is modeled with boundary loads. The soil assumes Drucker ... En savoir plus
In an alkaline electrolyzer stack, all cells share the same electrolyte. As a result of all cells being in ionic contact, parasitic shunt currents flow between the cells through the manifolds and the electrolyte channels, on both the inlet and outlet side. This example models a ... En savoir plus
When a linear guide is loaded above the manufacturer's specification limit, one concern is whether the contact loads will introduce fatigue spalling. In this system analysis, the entire guide has been analyzed and the mostly damaging contact load has been identified to occur on a rail ... En savoir plus
Electrodialysis is a separation process for electrolytes based on the use of electric fields and ion selective membranes. Some common applications of the electrodialysis process are: Desalination of process streams, effluents, and drinking water pH regulation in order to remove acids ... En savoir plus
This example illustrates the modeling of ply drop-off in a composite panel. The panel considered for the analysis has three sections–thick, taper, and thin. The thick section plies are divided into the core, top-bottom belts, and dropped plies. The thick section of the panel has sixteen ... 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
