Lithium iron phosphate (LFP) is a common positive electrode material in lithium-ion batteries. Specific for the LFP electrode material is that its equilibrium (open circuit) potential, when defined as a function of the lithiation state, features a large flat plateau with a more or less ...

A lab-on-a-chip platform can be realized on a rotating disc by designing channels and other features to use the Coriolis or centrifugal forces to manipulate the flow. These forces are controlled by changing the angular velocity of the disc, so the platform is programmed by using a ... En savoir plus
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
This tutorial shows how to use the Radiative Beam in Absorbing Media interface (Heat Transfer Module) to model the attenuation of a laser light going through a sample of silica glass, and the heat source generated by the absorption. En savoir plus
This simple tutorial model shows how to set up a parametric sweep over a number of frequency bands (octaves or 1/3 octaves) and remesh once per band. A frequency sweep is performed within each band, which now has an adequate mesh resolution. This approach saves some computational effort ... En savoir plus
In this model, you build and solve a 2D beam model using the 2D Structural Mechanics Beam interface. This model describes the eigenfrequency analysis of a simple geometry. A point mass and point mass moment of inertia are used in the model. The two first eigenfrequencies are compared ... En savoir plus
Use this app to validate that the default settings correctly submit jobs to a cluster. These default settings are taken from the preferences. The app allows you to override the default cluster settings, test modifications to the current setup, and test different settings for connecting ... En savoir plus
It is possible to engineer the structure of materials such that both the permittivity and permeability are negative. Such materials are realized by engineering a periodic structure with features comparable in scale to the wavelength. It is possible to model both the individual unit cells ... En savoir plus
Unwanted arcing can have serious adverse effects on electrical and electronic equipment and systems. To improve the understanding and prediction of arc dynamics, it is crucial to conduct multiphysics simulations of transient arc processes. This model features a 3D simulation of transient ...
