Conduction Loss (Time-Harmonic)
The Conduction Loss (Time-Harmonic) subnode allows you to model possible conductive losses in a Piezoelectric Material. The effect is only active in a Eigenfrequency or Frequency response study.
Conduction Current
By default, the Electrical conductivity σe for the media is defined From material. You can also select User defined or Linearized resistivity.
•
For User defined select Isotropic, Diagonal, Symmetric, or Anisotropic depending on the characteristics of the electrical conductivity, and then enter values or expressions for the Electrical conductivity σe in the field or matrix.
•
For Linearized resistivity the default Reference temperature T0, and Resistivity temperature coefficient αr, 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.
