[Gmsh] Gmsh crashes wile creating a mesh

[Moritz Nadler]

Thanks for your quick reply!

that's what I get when I try what you told me:

moritz at skynet:~$ gmsh test2.geo -2
Info    : Increasing process stack size (8192 kB < 16 MB)
Info    : 'gmsh test2.geo -2 ' started on Mon Jun 30 22:47:24 2008

moritz at skynet:~$ gmsh -rand 1.e-8 test2.geo -2

I have a 32 bit only OS and the gmsh version is:
moritz at skynet:~$ gmsh --version
2.0.8

Anybody any ideas?


Thanks and kind regards
