Inductor Bias Current Issue in Maxwell 3D and Q3D.

  I am using Q3D and Maxwell 3D and have an issue with both.
  
  1- In Maxwell 3D, I am simulating a square inductor, the goal is to change the bias excitation current and plot the Inductance vs. Current graph to get the saturation current value. I defined the current as idc and did a parametric sweep. The expected is to see a regular decrease in Inductance with increasing current; the result is somehow wrong; it starts with a considerable value when idc=0, then it decreases to a specific value at the first sweep step, and then it stays constant till the end of the sweep. Could somebody help with that?
  
  2- In Q3D, I am simulating the same inductor and plotting the inductance vs. frequency; however, when I try to change the bias current using Field Overlays > Edit Sources, it does not change in the results plot, it stays the original value which is about 1A. Could you help with this?
  
  Thanks.

  Hi,
  For Maxwell part, what is the solver you are using?
