[Gmsh] Cylinder in a box

[Alexandre Warnier]

Hello,

I'm trying to insert a cylinder in a box. I do not have any problem to
create the box but I have problem creating the cylinder with a .geo.
Everything seems to be working fine but I get the following error:



*Error   : Line Loop 9 is wrongError   : Line Loop 10 is wrongError   :
Line Loop 11 is wrongError   : Line Loop 12 is wrong*
with the last lines when I oppen it with gmsh.













*cl=50;x_min = -1000;x_max = 1000;y_min = -250;y_max = 250;z_min =
-250;z_max = 250;disk_x = 0;disk_y = 0;disk_z = 0;disk_d = 126;th=10;*
