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 Last edited by dokeun; January 27, 2012 at 02:31. |
