Hi Laila,

You could use the following approach:

- Solve in Maxwell and plot H field in ferrite to determine areas in the ferrite that aren't saturated (and therefore Polder approach is invalid).
- In HFSS, divide the ferrite into multiple 3D objects - one or more that represent saturated regions and one or more that represent unsaturated regions.
- For saturated objects, you may apply Polder tensor in material properties and Maxwell solution for bias
- For unsaturated objects, define appropriate complex tensor model in material properties

All material properties in HFSS can be defined as frequency-dependent models. Accuracy across the solved frequency band will depend on defining frequency-dependent material properties.

Start with the above procedure using default HFSS settings for things like order of basis functions and let us know how it goes!
