Hi, 

The material I am using is not a lamination and is a high resistivity material (so steel may not be a good description). Since I do not have BP curves, I cannot use core loss models in Maxwell.  

  1. From the loss tangent values I have, how to get the hysteresis losses (as in the formula or setting in ANSYS to get it). Integrating EM losses over the core volume yields very high values.
  2. If I set eddy effects to core (disable core losses) and add the experimental material resistivity/conductivity value - then how to calculate/retrieve eddy losses in the core (via fields calculator)?
  3. Please note that permeability and loss tangent values obtained from impedance analyzer are experimentally verified with VNA based Inductance and AC resistance values. So I don't think my loss tangent values are wrong, and am fairly certain that my setup in ANSYS or formula for getting the hysteresis losses are wrong.  Please let me know if you need more information
