Configuring Frequency-Dependent Conductivity and J-E Curve in AEDT HFSS

  Hello everyone,
  I'm working in Ansys HFSS (solver type: Transient) and have attempted to first set up frequency-dependent conductivity. However, I’ve encountered the limitation that, by doing so, I no longer have the option to also configure the J-E curve (nonlinear conductivity dependent on the electric field). My goal is to model material ionization under a lightning impulse, which requires both dependencies simultaneously.
  Has anyone faced this same limitation in HFSS and found a way around it? Any advice on configurations or alternative approaches would be greatly appreciated.
  Thank you in advance!

  This is a limitaiton of the software. - HFSS provides a linear solution to Maxwell's equations.
  Non-linear EM phenomena like ionization can be modeled with a different tool: Ansys Charge
