Gmsh is crashing after change Extrude value from 10 to 100

[Motox1982]

Hello,

here is my geo script of gmsh: (windows10 64bit)

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, allready fixed!

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

Welcome to PF.

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 wich 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 wich 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!
