Hi,

I created an stl file and try to run surfaceFeature Extract and It says the stl file is not closed.

Create time

Reading surfaceFeatureExtractDict

Surface            : "propellor.stl"


Feature line extraction is only valid on closed manifold surfaces.


--> FOAM FATAL ERROR: 
Cannnot read "/home/student/Desktop/propellor/constant/triSurface/propellor.stl"

    From function bool Foam::triSurface::read(const Foam::fileName&, const Foam::word&, bool)
    in file triSurface/triSurface.C at line 360.

FOAM exiting

Then I ran surfaceCheck. which says the surface is closed.

Reading surface from "propellor.stl" ...

End

Could anyone help to solve this..??

Thanks,
