kyfrankie New Member Kyfrankie Join Date: Oct 2020 Posts: 5 Rep Power: 5	Hello guys. I am trying to run a NACA wing CFD at RE100k with PimpleFoam inpiso mode. The mesh is generated by Fluent meshing and it is a poly-hexcore mesh. However, I discovered that at the corner, the BL has quite a small cell which leads to high CO there and long run time. In order to reduce the run time, can I adjust the MaxCo to 2 or more because the CO for other parts of the wing is quite small. Or is there any techniques to improve the BL cell at the corner?
