Error in meshing a Ship hull using snappyhexmesh
 
Iam working on a customized hull.when i used snappyhexmesh, i got the following error message:

Can anyone tell me what the problem could be?

I had to scale the geometry using convert to meter and the value was 1000.
The hull was modelled in Free ship and was imported to solidworks and was then converted to stl format, since the stl file generated from the freeship was just a half part of the symmetric body.

If anyone has encountered this problem, the reason is that you have a bad geometry file.
The stl files that you import from some of the cad softwares have this problem.
try importing a different geometry file.
