Dear all I am trying to use FreeCAD to make a 2d airfoil model and mesh it in gmsh. I would like some help on this.
I have loaded the airfoil coordinates using this macro https://github.com/FreeCAD/FreeCAD-macros/blob/master/ObjectCreation/Airfoil_Import_and_Scale.FCMacro This creates a BSpline. Then I have added more curves to define my domain. I want to specify the point distribution on these lines using "Transfinite Line". When I open the iges file in gmsh, I see that points are duplicated. End point of one line has different number than first point of next line. How to avoid this ? Should I define the surfaces in FreeCAD itself or in Gmsh ? Are there any examples available ? Thanks praveen
