Magnetic field simulations

Magnetic field simulations can be used to simulate magnetic field sources and determine and visualize their magnetic fields. This allows to evaluate and test optimal and customized shielding solutions. The software used are Edison – Low Frequency, COMSOL Multiphysics and Narda EFC-400.

Edison - Low Frequency

The Edison – Low Frequency software is a new and modern magnetic field simulation software. Thanks to latest software architecture, magnetic field simulations can be carried out in a modern and user-friendly software environment. The software enables a precise 3D visualization of electro magnetic fields, making it possible to assess whether limit values are complied with or exceeded.

Systron distributes the software in Switzerland, Germany and Austria. Further information can be found here.

We carry out magnetic field simulations for the following components and systems. If necessary, a suitable magnetic shield is designed by Systron.

COMSOL Multiphysics (3D FEM)

The Finite Element Method (FEM) is a numerical method for solving complex systems described by differential equations. Basically, the computational domain is divided into a finite number of subdomains, which in turn, due to their simplicity, can be well calculated. Based on transition conditions of the individual elements, the behavior of the entire system can then be calculated.

3D FEM simulations in Comsol allow to simulate the shielding effect of nonlinear magnetic shields. The shielding effect of shielding materials such as mu-metal, silicon iron, pure iron and aluminum can be accurately simulated and visualized. With the help of the simulation, the shielding can be designed and the effect can be verified.

With the 3D FEM software we perform magnetic field simulations for subsequent components. If necessary, a suitable shielding solution is designed by Systron.

EFC-400

Magnetic field simulatins in the Narda EFC-400 software for electrical installations and equipment allow 3D visualization of the propagation of magnetic and electric fields. This makes it possible to assess whether limit values are complied with or exceeded. The software allows the exact determination of electric and magnetic fields in the vicinity of electrical installations.
