This tutorial computes the transfer matrix of a tube and coupler measurement test setup. This type of setup is used for standardized testing, for example, for miniature loudspeakers or hearing aids. The Port boundary condition in Pressure Acoustics, Frequency Domain is used together ... En savoir plus
The flash method is widely used for measuring the thermal conductivity of a thin sample material that is about the size of a coin. The sample material is submitted to a laser pulse on one of its faces. In turn, the opposite face is heated up by around 1 K. As the pulse is uniform and ... En savoir plus
This tutorial demonstrates how to modify a concentration-independent (also known as a secondary current distribution) liquid alkaline water electrolyzer with concentrated electrolyte theory to explicitly resolve local electrolyte and solvent concentrations (thereby creating a tertiary ...

In complex mechanical systems, it can be challenging to find an optimal (or even good enough) solution only through engineering insight or trial-and-error procedures. Using mathematical optimization methods can then be an efficient path to a better design. In this example, a link ... En savoir plus
This model is based on the Metasurface Beam Deflector model. The performance is improved using shape optimization by allowing both the radii and the position of the individual pillars to change. En savoir plus
Anechoic coatings are used on submarines to reduce sonar reflections. This model calculates the reflection, absorption, and transmission properties of an anechoic coating on a steel plate. The calculated results from this sub-model can be used in larger system scale models, for example, ... En savoir plus
Cryer's problem is a three-dimensional consolidation benchmark. A porous sphere is subjected to a uniform boundary pressure. The pore pressure at the center of the sphere rises due to the Mandel-Cryer effect that is captured by a two-way coupling between Darcy's law and solid mechanics. En savoir plus
This model shows how to simulate the complex discharge physics behind the well-known electrostatic discharge (ESD). The model connects the Electrical Discharge interface with the Circuit interface to simulate how ESD current is generated when a human hand touches metal. En savoir plus
This proof-of-concept model showcases how to handle a Gaussian beam propagating in the negative y direction in 2D. The model includes several studies, including a parametric sweep, to cover a wide combination of settings describing the background Gaussian beam, such as settings for ... En savoir plus
The model of 1D Dielectric Barrier Discharge (DBD) has been recomputed with the three different kinds of electron energy distribution functions (EEDFs): The Maxwellian function The Druyvesteyn function The computed EEDF based on the Boltzmann Equation, Two-Term Approximation ... En savoir plus
