Quantum dots are nano- or microscale devices created by confining free electrons in a 3D semiconducting matrix. Those tiny islands or droplets of confined “free electrons” (those with no potential energy) present many interesting electronic properties. They are of potential importance ... En savoir plus
This example illustrates the principle of electrochemical polishing. The simplified 2D model geometry consists of two electrodes and an intermediate electrolyte domain The positive electrode has a protrusion, representing a surface defect. The purpose of the model is to examine how this ... En savoir plus
This example treats a pulmonary artery stenosis as a porous medium and demonstrates how to set up a model that combines free and porous media flow of a non-Newtonian fluid. The non-Newtonian behavior of blood is modeled using the Carreau model. En savoir plus
Follow this tutorial series to learn about how to work with imported surface meshes. The instructions detail how to import STL files of three vertebrae and two intervertebral discs as well as how to repair holes, misaligned mesh vertices, and intersecting elements. It further ... En savoir plus
This tutorial shows how to model transport of the individual ions in a salt melt comprising two binary salts, where the transport equations are defined using concentrated solution theory. The example model defines a molten carbonate fuel cell (or electrolyzer), with a 1D-model geometry ... En savoir plus
This tutorial model solves the incompressible Navier-Stokes equations in a backstep geometry using the Laminar Flow interface. A characteristic feature of fluid flow in geometries of this kind is the recirculation region that forms where the flow exits the narrow inlet region. The model ... En savoir plus
This example models an oil reservoir with two horizontal wells. The reservoir contains two phases, water and oil. Oil is recovered by injecting water through the bottom well, so the oil production rate and the water-oil production ratio over time are computed. En savoir plus
This model shows how to use the Metal Processing Module and the Optimization Module to calibrate parameters of a phase transformation model against TTT (Time Temperature Transformation) data. En savoir plus
This example extends the Fuel Cell Cathode tutorial to also include liquid water transport in the oxygen electrode. Liquid water is produced using a user-defined expression for vapor condensation, depending on the relative humidity level in the gas phase. An experimental capillary ... En savoir plus
This tutorial simulates a standard test and benchmark model for nonreflecting conditions and sponge layers for linearized Euler-like systems. It involves the propagation of a transient Gaussian pulse in a 2D uniform flow. The Convected Wave Equation, Time Explicit interface solves the ... En savoir plus
