I have a strange behaviour too...
The flowify command generates a huge model, with an array of sectional faces.

[attachment=2:17yhee20]<!-- ia2 -->flowify A.JPG<!-- ia2 -->[/attachment:17yhee20]
First the source material: Group 1 composed of A target surface / B source surface / C projection vectors and D the source mesh (exploded)

[attachment=1:17yhee20]<!-- ia1 -->flowify B.JPG<!-- ia1 -->[/attachment:17yhee20]
The resulting groups from the flowify command

I succeeded all the other meshes with the same method but here I've got a bug...
