So Im currently unsure, whether to trust the results of my Simulation or not. For me the downforce value (70N) , seems a bit high considering the wing isnt even in the near ground-effect region.
Also I checked my mesh and saw, that the boundary inflation layers arent resolved the way I was hoping for. You can see, that near the trailing edge BL-deletion begins to form. I read this article about preventing it, but Im not sure, what settings to change now in my meshing setup: FSAE Tutorial - Preparing Simulations For Success - Boundary Inflation Techniques And Y+ Validation.
Which y+ should you be aiming for? I was aiming for y+ = 1, but I also read, that you should be going for 30 < y+ <300. Also I was using just 5 inflation layers, but according to some forums k-w SST Modells should have around 20-25 layers to resolve velocity gradient correctly.
This i quite a lot to read and talk about, so I would be happy, if someone can just help me with one of the topics mentioned above.
