high order node distribution gmsh
 

Hello,
I'm trying to create a 2D 4th order mesh of a simple wing with gmsh. My problem: I can't get the nodes at the leading and trailing edge to be evenly spaced (see picture), even though the conectors at the edges are evenly spaced. I'm guessing gmsh is is trying to optimize the nodes for curved elements. Is there a way to avoid this?
Any help will be much appreciated!
