Vertical tail intersection on Panel Method

[Baizura Bohari]

Hi Rob and OpenVSP teams,

Can someone help me on this? I am trying to figure out why the attached model is not working on Panel method solution.
The problem might come from the intersection between the vertical tail and the fuselage since I was adding the parts one by one and run it.
It stopped working when I add the vertical tail and I have been looking all over trying to find the gap between the parts and still the solver stop at creating interaction lists.
This only happen with Panel code, as it works for the VLM solution.
I would really appreciates any input for me to move forward with the model.

Thank you,

Best regards,
Baizura

The airfoil files you used don't repeat the trailing edge point.  Consequently, OpenVSP sees that as a gap and fills it in using the same routines it uses to fill in a blunt trailing edge.

I changed all your airfoils to NACA 4-digit -- and I added some LE/TE clustering for the tail surfaces.  After that, I got this solution at 15 deg.

Thank you Rob for the solution. I would really appreciate if you can share the corrected files with me just to make sure I don't miss any point here. 

Thanks again.

Best regard,

Baizura

I'm sorry Baizura, I didn't save the file I got to work.

Give it a shot -- and feel free to ask again if you have more questions.
