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