Lifting Line Finished?

Finally the Lifting line problem writing in FORTRAN seems to be finished. Although I have my doubts with the method that is suggested by my Chinese colleague since it does not match the theory at all. I'll have to see what the professor thinks about it.

Killing Code

What should be an easy job is really killing me at this point.
The assignment of simulating a 2D Lifting Line I took on and was done coding in just 2 days. For some reason there seem to be a lot of bugs remaining. Not code wise but theoretical wise. Re-wrote the whole program about 4 times now. I still seem to be doing something wrong but I can't seem to figure out what. Will ask Mr. Gong (Chinese student supervisor) for some help. Hopefully he can give me some insight.
