Hello, I'm trying to import the geometry of an airfoil into gmsh and then mesh it. I'm using a python script to convert the coordinates from .dat file to .geo
I managed to succesfully import the geometry into gmsh, however when creating a plane surface an error occurs, saying:
Unknown OpenCascade curve with tag 1
line 34: could not add line loop

My geo file:

I would really appreciate any help.
