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?<\/p>\n<p>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 &gt; Edit Sources, it does not change in the results plot, it stays the original value which is about 1A.
