Frequency-Stationary
The Frequency-Stationary () study and study step are used to compute the temperature field, at thermal equilibrium, and the electromagnetic field distribution for models created with, for example, the following physics interface and module combinations:
•
Induction Heating interface, which requires the AC/DC Module,
•
Equilibrium DC Discharge interface, which requires the Plasma Module,
•
Microwave Heating interface, which requires the RF Module,
•
Acoustic Streaming with Pressure Acoustics, which requires the Acoustics Module,
•
Acoustic Streaming with Thermoviscous Acoustics, which requires the Acoustics Module, or
•
Laser Heating interface, which requires the Wave Optics Module.
It is a special case of a Stationary study in which the stationary heat transfer equation is solved together with a frequency-domain equation for electromagnetics. In addition to electromagnetic heating, the Frequency-Stationary study can also be used to compute other physics field such as force in which time-averaged Lorentz force is computed.
For other interfaces that support the Frequency study, like Solid Mechanics, set the equation form to Stationary in the main node of the interface when they are solved in a Frequency-Stationary study step.
