[Gmsh] 2D geometry: airfoil - spline, bezier or B-spline

[Nikola Zizkovsky]

Hi folks,

I have one problem (I hope only one).
I would like to mesh 2D airfoil...it's quite easy, but: I have to split this section for two curves.

Problem is that I have no idea how to keep tangency (and curvative) boundary condition. Well one idea is on the way: using bezier curve than spline, but here in Gmsh i can put only 4 nodes to bezier expression-list. So, is here any way how to put more than 4 nodes to Bezier?

Which type of BSpline is integrated? Uniformed/non-Uniformed ...

BTW: just now i have only spline nodes and I will have to count bezier nodes:-(

Thanks
Nikola Zizkovsky

PS> GMSH is very powerful tool
