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
Pitting corrosion is a type of localized corrosion by which local cavities, pits, are formed on an initially smooth metal surface. A pit may be initialized by surface defects, such as an inhomogeneities in composition or shape, or mechanical abuse resulting in a small scratch or dent. ... En savoir plus
Predicting the noise radiation from a dynamic system gives designers insight into the behavior of moving mechanisms early in the design process. For example, consider a gearbox in which the change in the gear mesh stiffness causes vibrations. These vibrations are transmitted to the ... En savoir plus
A Fabry-Perot resonator is one of the fundamental optical devices and has a broad range of applications. A few examples are that it can be used to measure length, frequency/wavelength or to filter specific spatial modes. This model uses the Beam Envelopes Interface in the bidirectional ...

In the chemical and biochemical industries, for instance in fermentation processes, reactors having well-mixed conditions and liquid level control are common. This example shows modeling of a 0D ideal system of tank reactors in series with controlled feed inlet and product outlet ... En savoir plus
A plane electromagnetic wave is incident on a metallic sphere partially embedded on a substrate. In this electromagnetic scattering problem, the far-field variables are computed for a few elevation angles of incidence. 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
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
This example models co-electrolysis of H2O and CO2 using a solid oxide electrolyzer cell. The model includes the full coupling between the mass balances and gas flow in the H2 and O2 gas diffusion electrodes, the momentum balances in the H2 and O2 gas flow channels, the energy balance ...

This tutorial shows how to evaluate the harmonic response of a structure with a moderately nonlinear behavior. A nonlinear problem can only be solved using time-domain analysis. A way to speed up the computation is to use a linearized frequency response analysis to provide good initial ... En savoir plus
