A highly simplified pedestrian bridge is for simplicity imagined to consists of a concrete slab on supported by three I-beams. The design is to be evaluated for peak acceleration due to walking. The model analyzes uncertainty in peak acceleration due to some material damping properties ... En savoir plus
Atmospheric corrosion occurs when metallic structures are exposed to humid air forming a thin electrolyte film in the range of up to a few hundred micrometers. The model presented here accounts for charge transport as well mass transport involving 10 species and 6 homogeneous ... En savoir plus
A wideband antenna study, such as an S-parameter or far-field pattern analysis, can be obtained by performing a transient response analysis and a time-to-frequency fast Fourier transform (FFT). This model runs a time dependent study first and then transforms the dependent variable, the ... En savoir plus
Free-surface calculations in the predefined flow interfaces are currently limited to time-dependent studies when using the built-in boundary conditions. Here, a stationary formulation following Romero et al. [1] is implemented using equation contributions. The attached slides describe ... En savoir plus
MOSFETs typically operate in three regimes depending on the drain-source voltage for a given gate voltage. Initially the current-voltage relation is linear, this is the Ohmic region. As the drain-source voltage increases the extracted current begins to saturate, this is the saturation ... En savoir plus
This model uses the Semiconductor and RF modules to describe a photoconductive antenna (PCA). A laser pulse is applied on the surface of undoped LT-GaAs to generate electron-hole-pairs, which move under the influence of an external E-field creating a transient electric current pulse. ...

This full-scale, time-dependent model of an offshore oil platform jacket involves modeling coating breakdown and estimating sacrificial anode life and the buildup of calcareous deposits on steel surfaces. The tutorial model aims to answer some of the common questions surrounding ... En savoir plus
An Evans droplet experiment is a century-old corrosion experiment for demonstrating oxygen transport-limited corrosion. A droplet of water is placed on a metal surface, and over time the surface features differences in the radial direction of the surface in terms of amount of corroded ... En savoir plus
The purpose of the app is to demonstrate and simulate the use of cyclic voltammetry. You can vary the bulk concentration of both species, transport properties, kinetic parameters, as well as the cycling voltage window and scan rate. Cyclic voltammetry is a common analytical technique ... En savoir plus
Using a Fluid-Solid Interaction multiphysics interface, the behavior of a spring-loaded ball check valve is studied under varying functional and reverse flow. The fluid force acting on the ball opens the valve at the opening pressure. In the case of a reversed pressure, the ball comes ... En savoir plus
