[Gmsh] gmsh fails to create points inside a loop

[jean pierre aubry]

hello

well,  that's exactly  it
thanks!!

i will have to be a little bit more clever in the design of the loops to
create the geometry in this case

it would be much easier  if i wecould tell

Line (10x) = Rotate [ .... {Duplicata { Line {100};}]
enforcing the value 10x instead of letting Gmsh use newl

a way of retrieving the number of the two ends of a line would be useful too

thanks again
