This model simulates an electrodeless lamp with argon/mercury chemistry. The low excitation threshold for mercury atoms means that even though the mercury is present in small concentrations, its behavior dominates. There is strong UV emission from the plasma at 185 nm and 253 nm. The UV ... En savoir plus
A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This model simulates splitting properties using a simplified 2D geometry. The computed S-parameters and electric fields at the lower and upper bands ... En savoir plus
This model demonstrates topology optimization for a problem involving acoustic-structure interaction for a sound partition problem. The objective being to reduce sound transmission for a fixed solid material fraction. The design domain is modeled with a mixed formulation using the Solid ... En savoir plus
Journal bearings are used to carry radial loads, for example, to support a rotating shaft. A simple journal bearing consists of two rigid cylinders. The outer cylinder (bearing) wraps the inner rotating journal (shaft). The new thin-film flow user interfaces of the CFD Module enables ... En savoir plus
A Fresnel rhomb is a prism that uses total internal reflection to manipulate the polarization of light. In this example, light in the prism is internally reflected at an angle of incidence that induces a 45-degree phase delay between s- and p-polarized radiation. By subjecting the light ...

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 model shows how you can implement a user defined hyperelastic material, using the strain density energy function. The model used is a general Mooney–Rivlin hyperelastic material model defined by a polynomial. In this example, you will see two material models based on the defined ... En savoir plus
This model presents a 2D simulation of transient arc discharge movement along guided copper rails. While accurately modeling transient arcs typically requires a 3D simulation, the 2D approach offers greater efficiency and remains valuable for initial investigations and demonstration ...

A simple model for groundwater contamination portrays a well that is bored into an aquifer. The aquifer consists of a partially saturated layer and a fully saturated layer. The model investigates how much of the contaminant ends up in the well after a contaminant is introduced in the ... En savoir plus
The model compare the electromagnetic force calculated by virtual work and maxwell stress tensor methods on the axial magnetic bearing. The forces is evaluated by studying the effect of a small displacement on the electromagnetic energy of the system. This is done by using the Magnetic ... En savoir plus
