An automotive midwoofer is modeled using the lumped parameter approach. The electrical and mechanical components are modeled using a lumped electric circuit, which is coupled to a finite element model for the acoustics using the Lumped Speaker Boundary feature. The large signal ... En savoir plus
This example models the temperature profile in a liquid-cooled prismatic battery pack during a high-rate charge. The pack consists of 16 prismatic battery cells connected by busbars, placed on an aluminum plate containing four cooling channels. The battery pack is assumed to have two ... En savoir plus

Thermal management of a battery pack is simulated considering two scenarios, air (natural convection) and phase change material (PCM) in the gap between the batteries. The PCM considered is a composite material of paraffin wax and graphite additive. Graphite is typically added for ... En savoir plus
Surface plasmon-based circuits are being used in applications such as plasmonic chips, light generation, and nanolithography. The Plasmonic Wire Grating Analyzer application computes the coefficients of refraction, specular reflection, and first-order diffraction as functions of the ... En savoir plus
This example shows how to image the interior permittivity of a box by applying a potential difference on the boundaries of the box. The result is a surface charge density that depends on the permittivity of the medium inside the box. Read about this tutorial model in our blog post "The ... En savoir plus
In electromagnetic simulations, such as transformers and converter stations, one often needs to include geometrically thin conductive layers. Explicitly meshing these thin layers can be computationally expensive and numerically challenging, especially when the layer thickness is much ... En savoir plus
This example simulates the temperature dynamics in cylindrical battery, initially at room temperature, after being placed in an oven. As the temperature increases, various exothermal decomposition reactions are activated, which in turn result in further heating of the battery. En savoir plus
