===Blocked Impedance Results at 1kHz===
Variation of the [[blockedimpedance|BlockedImpedance]] problem where the impedance and inductance of the [[http://tesi.cab.unipd.it/42449/1/Tesi_Lorenzo_Bortot_-_1014762.pdf|SSF-082]] loudspeaker are analyzed at 1kHz across a range of positions. Since the frequency is low (relative to 20kHz), a coarser surface mesh of 0.05mm can be used on the low carbon steel parts. Two configurations are considered: one with no shorting ring, and one with a copper shorting ring around the central pole.

Example scripts in Mathematica, Matlab, and Lua are available below in the Files section. The results of the analysis are pictured below in Figures 2-6.
