Boundary Condition for Normal extrusion (C grid)
 

Hello!

I am trying to generate a C-mesh for a NACA 6 series airfoil on Pointwise. So far, I have imported geometry of airfoil and created a horizontal line from the trailing edge to far field. When trying to extrude, I want to set a constant X boundary condition at the far field of the trailing edge wake. However, because the edges for the normal extrusion include selecting the horizontal line twice (one for extruding upwards and one downwards), I can only click the BC prompt once as they are both at the same location. This results in the BC being applied for the upper section of the extrusion only. Does anyone know how to go about this so that it can be applied to both sides? I have attached images of what this looks like. Thanks
