FastS/IBM: Turbulent Flow past a RAE2822 Profile

Turbulent flow simulation (Re=6.5millions) around a 2D RAE2822 profile at Minf=0.73 and 2.79° of angle of attack.
Spalart-Allmaras turbulence model for interior points and Musker's wall model for IBM points.

Mesh

Octree + full IBM.

              Mesh (snear=1.5E-3). 7 blocks, 347 000 cells.


              Mesh (snear=7.5E-4). 97 blocks, 623 000 cells.


              Mesh (snear=1.8E-4). 176 blocks, 2.6M cells.


              Mesh (snear=3.E-5). 454 blocks, 7.5M cells.
