Hi all, I am relatively new to openfoam.

I am trying to mesh a propeller with the propeller tutorial, and i cad the propeller in solidworks before exporting it into the stl file and putting it in the constant/triSurface directory. I ran blockMesh first, then surfaceFeatureExtract, then snappyhexmesh.

I got this error when i ran snappyhexmesh.

Any help will be deeply appreciated! Thanks guys!
