D(E) law: models


This section deals with the D(E) dielectric behavior law from the perspective of the models provided in Flux.


The numerous models provided are presented in the table below.

Isotropic/anisotropic material: linear approximation
Linear isotropic Linear anisotropic
Linear isotropic with losses (tan δ ) Linear anisotropic with losses (tan δ )
Isotropic/anisotropic material: nonlinear approximation
Isotropic spline No anisotropic model

Specific models are also provided (see table below). Their mode of use is presented in § Spatial model / user model.
