Normal lines to airfoil surface
 

Hi!

I am trying to create velocity profile plots for the flow over an airfoil in ANSYS fluent. from my understanding, the best way to do this is to create a line normal to the airfoil surface at the desired points and then create a chart of velocity against y using the normal line.

My problem is that i am unable to create a line that is normal to the surface. it seems that in older versions of ANSYS fluent there was a 'normal' option when generating a line, which i cant seem to find in the 2020 version.

I am sure there is something very simple that i am missing but i cant seem to figure it out. I would greatly appreciate any help you can give!

Kind regards,
Aoife
