Hi Chris,

Javatc and Fantc both run closewound or spacewound coils and will account 
for high frequency current distribution.

The programs however assume circular wire. Both programs use Paul's Geotc code.

Geotc solves for several L and C parameters as discussed in pn1401 and pn2511

Take care,
Bart
