Hello everyone,

I am trying to run snappy on my STL files but I have this error message.
Apparently, it cannot find "Cannot determine normal vector from patches"
I have already check the concerned twoDPointCorrector.C file and it comes from this :

if (mag(pn) < VSMALL)
    {
        FatalErrorInFunction
            << "Cannot determine normal vector from patches."
            << abort(FatalError);
    }
    else
    {
        pn /= mag(pn);
    }

This is the error I get :

    The number of points in the mesh is not equal to twice the number of edges normal to the plane - this may be OK only for wedge geometries.
    Please check the geometry or adjust the orthogonality tolerance.

etc......

Does anyone has any clue ?
Thanks for helping !
