Single turn coils produce AC and transient magnetic fields in pulsed magnetic technologies for which magneto-harmonic and transient magnetic analysis can be primarily performed. We suggest studying one single turn coil example made of a conducting massive coil, an optional conducting ... En savoir plus

Modern electrical vehicle motors require a precise current control over the rotation of the rotor. These motors have high performance, but their control requirement impose a precise knowledge of the rotor angular position. Rotor position sensor (RPS) are traditionally designed using ...

Micro-lenses with potential applications in optics on the surface of the various heavy-metal oxide glasses were created and studied experimentally [1-2]. Laser direct writing using continuous-wave laser emitting at 447 nm was successfully performed [2]. The aim of this study is to ... En savoir plus

Outline of presentation: In electromagnetic technology applications the finite element method is very well suited for a wide range of problem types For many cases, in particular when inhomogeneous materials having complex properties are involved as well as when multiphysics couplings ...

The wide bandgap semiconductor silicon carbide (SiC) has drawn increasing attention in recent years as a promising material for high-power, high-frequency, and high-temperature operating devices. These outstanding properties of SiC make it a good candidate to replace silicon in many ... En savoir plus

Plasma, a complex fluid consisting of electrons, ions, neutrals, and excited species, exhibits both fluid-like behavior and electrical conductivity due to the presence of charge carriers. Consequently, computational modeling of plasma requires the integration of fluid and electrical ... En savoir plus

Simulation of laser processes are more and more efficient. In some cases, as welding and additive manufacturing, the physical phenomena are complex, multi-physics and multi-phases, thus some assumptions have to be done. For Laser Powder Bed Fusion, a laser beam melts and vaporizes the ... En savoir plus

Optical devices are generally simulated using ideal structures. These ideal geometries are critical in finding major features of the optical response. Unfortunately, fabrication of such devices rarely results in structures that are ideal.[1] In particular, surface roughness is rarely ... En savoir plus

Transition metal dichalcogenides (TMDCs) have attracted the interest of researchers because of their physical properties, such as tunabilitiy, non-zero bandgap, gas sensing and superconductivity. One of the most studied TMDC is monolayer MoS2, for this reason we present how COMSOL can be ... En savoir plus

In this study, for the first time, we have carried out three dimensional transient magnetostructural analysis of a Magnetic Pulse welding (MPW) system which welds two tubular work pieces of dissimilar conducting materials. For this purpose a finite element model (FEM) is developed using ... En savoir plus
