Hi,

I'm trying to create a rounded trailing edge with a radius of 3 mm on a airfoil setup with 3 elements. The individual elements are Line Bodies created with 3D Curve from imported coordinates. The coordinates of each element ends like in the example below:

Code:
...
1 65 0.741569 -0.370387 0.000000
1 66 0.783980 -0.382998 0.000000
1 67 0.820996 -0.393223 0.000000
1 68 0.852138 -0.401242 0.000000
1 69 0.877052 -0.407157 0.000000
1 70 0.895357 -0.411035 0.000000
1 71 0.906638 -0.413040 0.000000
1 0
I tried using Vertex Blend to fillet the trailing edge, but there is no vertex to select at the trailing edge. I also tried sketching it manually, but I can't set the tangential constraint on both the upper and lower side since there is only 1 edge on each element.

Does anyone know how to fix this? Maybe there is a way to create a vertex at the trailing edge?

Thank you.
