Avoid the use of 0 as point or line number. That should solve your
problem.

Hi all,
I have a problem with a mesh that I am trying to create
for a torus.
Specifically, it is a problem with a quadrilateral on the
surface.
I copied it out of the torus file
and put it in the .geo file below
//----------------------------------------------------------
Point(200) = {0.47099,0,0.19509,l};
Point(0)={0.509796,0,0,l};
Point(1)={0.548601,0.191342,0,l};
Point(201)={0.506842,0.191342,0.209941,l};
Line(400) = {200,201};
Line(0)={0,1};
Line(200)={0,200};
Line(201)={1,201};
Transfinite Line{0,200,201,400} = 5;
Line Loop(3) = {0,201,-400,-200};
Ruled Surface(3) = {3};
Transfinite Surface{3} = {0, 1, 201, 200};
Recombine Surface{3} = 45;
//---------------------------------------------------
I am getting the error
Error : Something wrong in edge loop computation
Error : Surface 3 is transfinite but has -1 holes
Could anybody tell me what this error means and what
I can do to alleviate it.
This is part of the surface of a 3d mesh I am trying to
make for a torus
using hexahedrons. I am trying to make "nice"
quadrilaterals on the surfaces like this one (just like in
the hex.geo file)
so that I can get nice hexhadrons for the 3d mesh, but I
am running into
this problem.
Thanks for your time,
Dan
