GAMBIT - problem with Boundary layer meshing

MartinRei · October 23, 2011, 10:23

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.

While generating BL click the Internal Continuity and Wedge Corner Shape. If you meshed using gambit

Or mesh block by block
leading edge separately,trailing edge,etc
