Hello
I have a trouble during managing branch cut of doubly connected domain.
Now I'm refering page 391 of CFD VOL I written by Hoffmann.
After excution of the program, I found that I had a bended tip at the trailing edge. According to the equation 9-77, y(1,j) is calculated then y(IM,j) = y(1,j). But it yeiled a bended trailing tip as pics attached(there are zipped). So I had to make y(1,j) as zero by force to get reasonable y coordinates(I mean zero points)

Should the original algebraic grid has zero point at trailing edge?! I mean x,y at trailing edge is chord/2,0
