@murillocs - alright, I found your project and had a quick look. I guess you’re referring to this project: https://www.simscale.com/projects/murillocs/front_airfoil_formula_sae
In your mesh settings, you added refinements where you allow the a maximum refinement of level 9 (see screenshot).
These levels refer to the octree-refinement approach. This means with each level, one cell is split into 8 cells. So if we make this computation for 9 levels, we end up with:
$$ 1 \cdot 8^9 = 134217728$$
So even if only one cell would be refined to a level of 9, you’d end up with a huge number of cells that can not be handled anymore by a reasonable machine. Therefore, I’d suggest that you rather start with a max level of 5 or 6 and see if you really need a higher level of refinement.
Another question: What CAD software did you use to create the wing? It looks great - but the many split faces on the surface are odd. It would be nicer if this would be one nurbs face, so the export seems to be split those faces…
