[Gmsh] Error Remeshing STL to Generate QUADs/HEXAs

[David Colignon]

Hi,

read carefully the output:

...
...
  Info    : Done creating topology from mesh (0.799456 s)
  Error   : 'Offset_mesh.geo', line 9 : syntax error (Recombine)
...
...


you forgot the ";" after Mesh.RemeshAlgorithm=1
so you get a syntax error on the next line: Recombine...

Regards,

Dave
