7 years ago This may be easier to implement in your meshing software, as the continuity in the loft is likely to not be as good if the curves are split. You'll probably want to use a multiblock mesh and split it at certain locations, but I think this something that needs to be done in the meshing software. I can't really provide support for that as I haven't tried it at all. I did briefly try to create a an inviscid panel method style wing mesh in gmsh using a 'Bump' progression to make it finer at the LE, but that's probably not much use to you:
I'd like to use SMESH for doing this eventually from within python, at which point it would make sense to provide support for quilting the Bspline surface and multi-block decomposition, but it's not currently supported (I mentioned this in #18). @jf--- is there any update on that?

Hi Paul, This may be a feature request, Since some times it is really important to make use of the leading edge point, or control the upper and lower cuves individually, (e.g adjust the grid distribustion in CFD according to the upper and lower curves), two upper and lower curves may be a better choice of a whole curve. I've tried to implement this using pythonocc, though I'm greenhand of it and failed to use BRepBuilderAPI_MakeEdge to trim the airfoil curve for not finding the leading edge point on the geometry curve. Some times it can work by useing the gp_Pnt(0., 0., 0.) to cut the curve, but most cases this point is not on the curve and will return an error, even the datasets used to interpolate the airfoil curve contains a [0, 0, 0] coordinate.
