Conduction Loss (Time-Harmonic)
This feature requires the Acoustics Module, MEMS Module, or the Structural Mechanics Module. See the individual documentation for information.
The Conduction Loss (Time-Harmonic) subnode allows you to model possible conductive losses in a dielectric material. The effect is only active in a Eigenfrequency or Frequency response study.
Conduction Current
By default, the Electrical conductivity σ for the media is defined From material. You can also select User defined or Linearized resistivity.
•
For User defined select Isotropic, Diagonal, Symmetric, or Full depending on the characteristics of the electrical conductivity, and then enter values or expressions for the Electrical conductivity σ in the field or matrix.
•
For Linearized resistivity the default Reference temperature Tref, and Resistivity temperature coefficient α, and Reference resistivity ρ0 are taken From material, which means that the values are taken from the domain (or boundary) material. T is the current temperature, which can be a value that is specified as a model input or the temperature from a heat transfer interface. The definition of the temperature field appears in the Model Inputs section.
