Well, happyjack27 had an idea* about what I call chain-link. I've just added support extensions:
Leaving the problems of how to power and cool the six primary coils. I might think about SC and coolant paths between the primary coils and support coils.
Only eight extensions are shown, but it could easily be twelve.
*Taking a bit of my own advice, I've been reviewing the earlier posts on this thread. I don't think this a completely new idea.
I think so, but no need for nubs (nurbs, etc.). If the support legs are splayed (which I will show later), there is no need to keep them separated by interfering matter, either.
The "splay" angle is about 13.5 degrees. Twenty-four close approaches v. twelve for the WB-6, 7 & 8. It is worse from a point cusp perspective, but I think the structural simplicity and the confinement from the octahedron shape might make it worth the trouble.
It’s been ‘bout a year or two since my last post here guys. Anyway, here’s some screenshots from the latest version of my 3D magnetic field line rendering program. I couldn’t find any example programs on the internet which showed me how to plot the 3D magnetic field lines (magnetic flux density lines – B lines) generated by 3D electrical current conductor sources. So I started from the only 2D example code(s) I could find and figured out the rest from there. With this program, you can drag the 3D conductors and their associated 3D magnetic field line images with your mouse to see them rotate together about the origin (core) in real-time. The program is still in development mode. I’ve discovered that 3D magnetic field line rendering is in “NO WAY” a science yet – it is still an art form… The exceptions you have to make to reasonably render a recognizable magnetic field image are enormous and almost always different for each rendering. You simply cannot plot all the information at once – it’s too mind-boggling. You’re better off learning how to plot only certain subsets of the 3D magnetic field lines in question. In 2D, magnetic field lines (B-lines) form closed loops. In 3D, magnetic field lines (B-lines) generally – never end! What I’ve learned so far is that the field shape you really get doesn’t look like what you thought it would - there are subtle and important differences. But after you study what you really get (for a while) it makes total sense. ~Randy
Don't know what I did wrong. But only the links to the images posted. Maybe someone here can re-post the images or instruct me on how to properly post such things from 'Photobucket'. It's been a long time since I posted stuff from photobucket. ~Randy

I just uploaded the program source code to ‘Planet Source Code’. However, you will have to wait a few days for the PSC moderators to approve and post the code. Just keep checking the PSC site and the code will become available in a few days.
* Go to http://www.planet-source-code.com/
* You will have to register at Planet Source Code to download files.
* Enter: RandyT_CS in the Search Term… box and click the search button.
* Select the Magrid 1.0 file from the list that comes up and download the source code from there.
