<div class="">Dear Geoffrey,</div>
<div class=""><br class="">
</div>
That’s a bit more complicated.
<div class=""><br class="">
</div>
<div class="">Wounded inductors (bobbins) are usually accounted for with a magnetodynamic formulation, that means resistive and inductive effects accounted for.</div>
<div class="">In a full wave formulation, you would have everything, resistive, inductive and capacitive effects, but it is expensive and may be unstable for low frequencies.</div>
<div class=""><br class="">
</div>
<div class="">You may also combine/couple two different formulations, a magnetodynamic formulation and an electrostatic formulation.</div>
<div class="">For the details, have a look at the following paper:</div>
<div class=""><span style="font-family: Times; font-size: 10pt;" class="">Patrick Dular, Ruth V. Sabariego, Patrick Kuo-Peng, (2006),"Three-dimensional finite element modeling of inductive and capacitive effects in micro-coils", COMPEL: The International Journal
for Computation and Mathematics in Electrical and Electronic Engineering, Vol. 25 Iss: 3 pp. 642 - 651 </span></div>
<div class=""><br class="">
</div>
<div class="">For the implementation: you may mix the inductor model (onelab) and the one you already have.</div>
<div class=""><br class="">
</div>
<div class="">Regards,</div>
<div class="">Ruth</div>
