Gmsh OpenCASCADE merged my wing profile
I want to mesh my AGARD 445 wing in Gmsh and then simulate it in solver, so I merged the igs file in Gmsh and add the domain and boundary via GUI of Gmsh. However, the volume cannot be added, it seems like the surface boundary is not closed. So I wonder if there is a way to transfer geometry of my merged igs file, into the controllable points, spline and surfaces in Gmsh? If I have the coordinates direct in Gmsh scription I can easily detect where is not closed.
Or how can I just close the boundary in other ways? Here I provide with my geometry file, Please help me to create mesh corretly of the wing.
