The Challenge EM Simulation

Are you faced with such tasks: Are innovations permanently required? Measurements and experiments are not satisfactory? Is the Physics Complex? Time is short? Then we are here for you! On these pages we demonstrate MAGNETICS, an outstanding electromagnetic FE solver product that we develop for you. MAGNETICS, integrated in NX / Simcenter or as standalone, well known as NX Magnetics, is a comprehensive FEM software package to simulate and optimize electromagnetic devices. It is used by industry and science and either… Read More
Circuit Breakers

Outstanding Features for the coupling of electromagnetic, elasticity, motion and thermal allow realistic simulations of circuit breakers and switchgears. The animation demonstrates the FEM simulation of a low-voltage circuit breaker. A voltage is applied to a coil (below), whereupon the plunger is pulled into the coil. The four contact bridges (above) are connected to the plunger and then press on their contact partners, whereupon the AC current flows through the lines. The Lorenz forces lead to small mechanical vibrations with… Read More
High-Frequency

Thanks to the capability of a full wave solver, the analysis of antennas, waveguides or microwave ovens is another application area for electromagnetic simulation with Magnetics for NX/Simcenter. The picture shows as an general example the model of a microstrip patch antenna and its electric field result. Such antennas are becoming increasingly useful because they can be printed directly onto a circuit board. They are becoming very widespread within the mobile phone market. Patch antennas are low cost, have a… Read More

Lightning Strikes

Lightning strikes that occur in wind turbine towers can be analyzed to help for dimensioning of arrestors and to estimate the electric and magnetic field strengths that appear.This example shows how this kind of analysis can be done in Magnetics for NX/Simcenter. The tower is made of steel bars that conduct the lightning current down into the ground. Inside is a cable with an resistor in which we want to analyze the specific energy.
