Thanks for your help.
I set the red sizing to soft and it helps with the boundary layer:
The problem is that it destroys the mesh in front of the airfoil:
Also now the cells also shrink towards the top edge of the domain which I don’t want. That’s also why I left the other sizings “hard” or else they’d also grow from both sides.
Another way to stop them growing like that seems to be to set the global sizing to “Use Adaptive Sizing”, but then i have the issue with the inflation layer again and the mesh is also broken:
I’m using 2021R1, but I can upgrade if you think that helps
