Hello,

here is my geo script of gmsh: (windows10 64bit)
Code:
Point(1) = {0,-35,20};
Point(2) = {0,-35,-10};
Line(1) = {1, 2};
Point(3) = {0,35,-10};
Line(2) = {2, 3};
Point(4) = {0,35,20};
Line(3) = {3, 4};
Line(4) = {4, 4};
Point(5) = {0,0,0};
Line(5) = {4, 5};
Line(6) = {5, 1};
Line(7) = {1, 1};
Line(8) = {1, 1};
Curve Loop(1) = {1,2,3,4,5,6,7,8};
Plane Surface(1) = {1};
Extrude {10, 0, 0} { Surface{1};  }
ReverseMesh Surface{1};
Mesh 2;
it works fine!

but if i change the line to: Extrude {100, 0, 0} { Surface{1}; }

(only changing value 10 to 100)

gmsh is crashing!
what is the problem, anyone any ideas?

regards, mario

omg, already fixed!

Line(4) = {4, 4}; and some stuff, it was a long day ;-)

Can you post your updated script so we can see what-all you changed to eliminate the errors? Was it just the definition of Line(4) that was the problem? And why did it work like that with the coarser mesh for Extrude?

Thanks.
 
The Problem was the Line which have the same Point Numbers such as:
Line(4) = {4, 4};
Line(7) = {1, 1};
Line(8) = {1, 1};

It was auto generated by my tool which uses gmsh, i though it was a gmsh error, but it was mine, everything works fine now!
 
Still, the program should return an error instead of crashing. But man does it crashes quite often!
