Voltammetry at a Microdisk Electrode
Voltammetry is modeled at a microelectrode of 10um radius. In this common analytical electrochemistry technique, the potential at a working electrode is swept up and down and the current is recorded. The current-voltage waveform ("voltammogram") gives information about the reactivity and ... En savoir plus
Die Forming
Die forming is a widespread sheet metal forming manufacturing process. The workpiece, usually a metal sheet, is permanently reshaped around a die through plastic deformation by forming and drawing processes. Simulations can be carried out in order to avoid cracks, tears, wrinkles, too ... En savoir plus
Elastoplastic Analysis of Holed Plate
This example shows the analysis of a perforated plate loaded into the plastic regime. Part of the example is a benchmark, which you can find in section 7.10 of The Finite Element Method by O.C. Zienkiewicz. The unloading of the plate and residual stresses are also studied. In a second ... En savoir plus
Contaminant-Removal from Wastewater in a Secondary Clarifier by Sedimentation
Wastewater treatment is a several-step process for removing contaminants. Firstly, large, solid particles are removed through sedimentation, flotation, and filtration. And then in a second step, biological treatment causes the smaller particles to aggregate, forming so called flocs. ... En savoir plus
Ultrasonic Car Parking Sensor
This tutorial demonstrates how to compute the response of an ultrasonic car parking sensor transducer coupling Pressure Acoustics, Frequency Domain, Solid Mechanics, and Piezoelectric Materials. The far-field radiation pattern of the transducer is then used as a source for a Ray ... En savoir plus
Stress Analysis of an Elliptic Membrane
This is a benchmark model for a plane stress problem. The accuracy of the computed stress concentration is evaluated, and a mesh convergence study is performed for different element types. En savoir plus
How to Generate Randomized Inhomogeneous Material Data
These examples demonstrate how to generate and visualize randomized material data with specified statistical properties determined by a spectral density distribution by using the tools available under the Results node. In the blog post associated with these files, "How to Generate ... En savoir plus
Three-Port Ferrite Circulator
A microwave circulator is a multiport device in which a wave incident on Port 1 is coupled only into Port 2; a wave incident on Port 2 is coupled only into Port 3; and so on. Circulators are used to isolate microwave components, for example, to couple a transmitter and a receiver to a ... En savoir plus
Anechoic Chamber Absorbing Electromagnetic Waves
An anechoic chamber is used to measure antenna characterization, electromagnetic interference (EMI), and electromagnetic compatibility (EMC). Within the chamber are absorbers that are configured with an array of pyramidal objects that steer the propagating incident field onto their ... En savoir plus
Conical Quantum Dot
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
