RAE2822 convergence
Hi all,
I have some problems with the testcase "rae2822". The original case is the case 6 of RAE2822 and it works well. But when I am trying to study the case 9 by only modifying the mach number and the angle of attack (0.734 for Mach and 2.79 for angle of attack), the solution can be poorly convergent and not stable at all. Can anyone give me some advise ? Any helps are appreciated. |

According to AGARD paper, and other papers, the Reynolds Number is almost the some. In case 6, I'm using a mach number of 0.729 and an angle of attack of 2.31 and, for case 9, a mach of 0.734 and angle 2.79. My y+ is 2.6 (above 1) and the turbulence model is Spalart-Allmaras. I attached my configure file. thanks for the help. Joao Attachment 59800 |
