"... They might be even worse than DD coil shape..." - This is an interesting claim!
I would like to hear an elaboration on this claim.
Keep in mind that I am a layman and I will need an explanation as simple as possible.
Thanks in advance!

Well,

I could render the image internally in a much high resolution and shrink it to the screen size. Aliasing effects would be less visible.
On the other hand, my frames-per-second rate (FPS) for real-time displaying would suffer.
Yes, I can rotate, move, scale the display in real-time. Even flying around through the coil configuration. This is what you can't see.

The cross-sectional area of the DD shape is certainly larger than that of the OO (if we take the same final diameter of the entire coil).
But the geometry is less regular.
The O shape is "perfect" and the assumption is that the interaction between the two OO coils will be more perfect and easier to predict than with the intersection surface of the DD shape.
This is a basic assumption that has so far proven to be true in reality.

Yep, the proof is in the pudding.
We have to make the analysis to see the evidence.
But not yet. I have to solve some issues with the coil software.

I'm just asking you not to rely too much on AI hallucinations!
...
EL Nino is not as naive - as it seems!
When you answer his question; be careful because you are walking on an unmarked minefield!
I have personally seen EL Nino develop his biceps by constantly walking huge OO coils around the fields!
He knows very well what he is asking you!

Ok guys,

I have solved the 3d spline interpolation now.

But it produces a lot of wire filaments now. Look how smooth and fine the coil geometry now is. Single loop contains 200 wire pieces. There are 1000's of wire filaments.



Now the following D shape is reduced to 6 interpolation wire filaments and then increased again to 100 wire filaments.
Nice.

Seems to work fine now.

I have to solve the dilate/contract issue next time.
Cheers,
Aziz

This is the finaly result of the latest DD coil configuration with the 3d spline interpolation (100 wire filaments per loop count). The wire filaments have approx. the same length before dilate/contract.

I should be able to model fusion reactor coils now.

As long as I've been watching the project, I can't answer the question: how will all this help ordinary mortal coil manufacturers?)))

[ivconic]

I don't know how it will help you, but it has helped me a lot for a long time; I don't DIY coils for 10+ years: I use various original stock coils!

Hi JoyJo,

As long as I've been watching the project, I can't answer the question: how will all this help ordinary mortal coil manufacturers?)))

I don't know. They don't contact and ask me.

It is also getting difficult for after market coil manufacturers. The new coils and detectors have a chip built-in (in the coil plug) to prevent after market coils.

No good.

[ivconic]

Some Russians, Chinese and others have already solved that.
All those "smart" and rather mystified coils have already been dissected in all possible ways and the complete (epoxy filled) content of such a coil has long been known.
In principle there is no secret; usually some top specs opamp is present and often some MCU which serves to prevent the use of such stock coil for other purposes.
The most pathetic example is the newer series of ML coils for the Vanquish-Equinox-Manticore models.
But that's not all! Now I risk creating problems for myself; because I will say that the GPZx coils were totally "debunked" until the last one.
All my general pessimism comes from such knowledge. The more I know, the more pessimistic I am.

[Aziz]

Good news regarding dilate/contract feature!

Google AI made it perfect now. I gave him thumbs up!


Now this is looking like a real coil bundle. The 3d cubic spline + dilate/contract features have been finalised now.

[Aziz]

Very nice.

Watch out, you might convince Ivica that AI is actually useful!

[Aziz]

Damn it! AI makes bugs.
It doesn't work, if z-coordinates vary.

My own work-around works however.
