Hello, I'm a recent arrival at Maple Primes (as in earlier today), and I seem to recall a much older version of either Maple, Matlab, or Mathematica having a 3D plot example of a "Schauberger" tube. I've looked through my old files and can find nothing. These are similar to a tornado or water whirlpool profile, so I'm supposing that cylindrical coordinates are a suggested goemetry. A "decaying radius" spiral looped inside the "Gabriel's Horn" elsewhere on Maple Primes has a similar 3D profile, but the pipes that Herr Schauberger patented in Austria long ago also decreased in pipe diameter as the spiral radius decreased inward.
