Statics and Low Frequency

Structures which are very small in comparison to a wavelength can be simulated with low frequency or even static tools. Classical low frequency applications comprise motors and generators, switches and valves, sensors and actuators. Here, not only the electromagnetic fields, but also force, torque and temperature are relevant.

Besides the design of such devices, other parameters can be studied: Will the shielding be sufficient or the breakdown voltage be reached? It is also important with respect to labor protection to calculate a human’s exposure when working next to a high field strength device such as an electric welding machine. Since the definition of low frequency is relative, there are applications like PCBs or MEMS which still may belong in this application range.

CST EM STUDIO™ (CST EMS) covers the low frequency section of CST’s EM simulation range. It features a set of solvers dedicated to the various application classes. A thermal solver is also available. This can be coupled not only to CST EMS, but also CST MICROWAVE STUDIO® (CST MWS) and CST PARTICLE STUDIO™ (CST PS) for further evaluation of simulation results.
