I'll get on to these at some point soon. After a bit of fiddling I came up with a primary for your test coil which give a k around 0.3, a little over if anything. Made of constraint of achieving this k while keeping the same primary inductance, so I can keep Cpri the same too. Had to use a cylinder primary to do it, and a close one too. Its running through the machine now...in fact a waveform has just popped out and its horrendous. Nothing like a familiar beat. http://www.abelian.demon.co.uk/tssp/tmp/tplot.4470.out.gif The normal modes are interesting, http://www.abelian.demon.co.uk/tssp/tmp/tplot.4513.gif which shows the current profiles. Note how modes 1 & 2 diverge near the bottom of the coil due to the heavy coupling. The thing probably isn't tuned correctly anymore and I need to go back and re-run it with a slightly different primary C. Meanwhile we have a mixture of over coupling and bad tuning to look at! Its getting a bit late here, so I'll tune and movie this coil tomorrow. > The raw data (big length vs time numeric array) would be cool > to have too. OK, I'll sort that out tomorrow, just need to document the format, then you can generate your own mpegs as big as you like. Now I've got this silly idea to run it through the ray tracer...
