Non Linear Field Dependant Permittivity

[shipstar]

Dear All,

I am trying to perform an analysis of a non linear permittivity material with electric field effect. I can perform the analysis with regards to temperature, but not electric field. Does anyone have any suggestions please?

Regards

The following inf. would help you

Elements with magnetic capability use the TB table to input points characterizing B-H curves. These curves are available in elements SOLID5, PLANE13, PLANE53, SOLID62, SOLID96, and SOLID98. Temperature-dependent curves cannot be input. Initialize the curves with TB,BH. Use TBPT commands to define up to 100 points (H,B). The constants (X,Y) entered on TBPT (2 per command) are:
Constant
Meaning

X Magnetic field intensity (H) (Magneto-motive force/length)

Y Corresponding magnetic flux density (B) (Flux/Area)

Specify the system of units (MKS, CGS, or user defined) with EMUNIT, which also determines the value of the permeability of free space. Free-space permeability is available in elements SOLID5, INFIN9, PLANE13, INFIN47, PLANE53, SOLID62, SOLID96, SOLID97, SOLID98, INFIN110, and INFIN111. This value is used with the relative permeability property values [MP] to establish absolute permeability values. The defaults (also obtained for Lab=MKS) are MKS units and free-space permeability of 4E-7 Henries/meter. If you specify the CGS system of units by Lab=CGS, free-space permeability is set to 1.0 (dimensionless). You can specify Lab=MUZRO to define any system of units, then input free-space permeability.
