STL problems
 

I'm trying to build a STL file from BLOC NOTE; assets after import STL file for FLOW 3D, it was put in the slot, and the figure is correct. but when I run the simulation an error message shows:

''' number of triangles processed successfully: 0
the last line read from input file:
facet normal 0.0000 0.2000 0.0000
error occurred when reading line:
0.0000 0.2000 0.0000


level 0 error in subroutine rdstl:
normal vector dataset error

level 1 error in subroutine cadstl:
error while reading stl file '''
