GAMBIT - problem with Boundary layer meshing
1 Attachment(s)
Hello everyone.

While trying to apply a boundary layer mesh to an airfoil, I encountered a problem.
It seems like the nodes at the leading edge are connected not by a spline but by straight lines so that the normal vector doesn't change from one node to the next one. When applying a boundary layer this then results in a non uniform mesh as shown in the attached picture.

Does anyone know how to fix that?
Thank you.
