High Voltage
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 low profile and are easily fabricated.
Simulations like that allow finding detailed characteristics.
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.
High voltage differences between conductor and isolator may lead to the risk of electric arc appearence. Therefore a FEM Analysis is performed to locate the position of a possible fault.
In this example two current carrying conductors and a permanent magnet are examined for the force acting on them. The nodal forces (Lorenz forces) are calculated in Magnetics for NX/Simcenter. Then the forces are transferred into a structural analysis where we calculate for deformations.
