PANAIR: PANEL METHOD CODE

February 21, 2003, 06:37

I would like to know if there exists any post-processor for "PANAIR (A502)" second order panel method based code. This code produces a very huge output file in ascii format. I am in process to develope the post processor and hence want to confirm if such post-processor exists or not. I have received this code from www.pdas.com which is version released in 1993. Can anybody help me in this reagard or provide more information? I would like to know if there are any users of this codes in INDIA.

Hi!
A little part of my master thesis consisted in writing a GUI postprocessor.
I did it in Matlab in order to expedit the process. Anyway, that is University of Pisa property (http://etd.adm.unipi.it/theses/avail...102009-175411/)
.
There are a couple of commercial tool too (Zonaair if I rememebr well), and other codes which were probably used times ago by the industries (Boeing...)

Just my 2 cents: the Post processor is quite easy and fast to implement, what it is really demanding is the the preprocessing.
Moreover, PanAir, as an higher panel method, don't admit any hole, and requires very sever abutment conditions.
And, it is not really efficient compared to a Low-order panel method.
I wouldn't recommend it, even if I used it a lot!
Ciao

Hi fulkrum!

I have sent you a private message. Please check it out and comback to me.

Thanks.

That's impressive! How long did it take to develop the whole (pre and post processing) Matlab GUI?

Thank you :-)
If I remember well, the longest part of the work was devoted to the NURBS fair minimization algorithm and the structured mesh generator.
Pre and Post processor weren't the most difficult part, I can't remember exactly, but it probably took me 11/2-2 months (considering the fact that I had to learn PanAir and I had to learn how to program GUIs).

lovecraft22 · February 2, 2014, 06:59

11 months is not bad at all to program such a thing in Matlab! Congratulations!

fulkrum · February 2, 2014, 15:19

Eheh, actually I meant 1 and 1/2 - 2 months.:-)
Thank you anyway :-)

lovecraft22 · February 2, 2014, 16:07

Well, congratulations then! Don't know how deep the code goes behind the GUIs, but it looks like a lot of job anyway.
Is it robust in the end? And can the different GUIs interact/share data with each other?

Thanks again.
After I was done with the work, I and the other guys used it. Obviously there were occasionally some minors bug, but overall the process was very straightforward: geometric design, meshing, call to solver (through the preprocessor) and results visualization (post-processor). Obviously, the different GUIs were interacting, so that the whole process was basically carried out in the same framework.
