Good evening

i have a problem with my results in ansys fluent as i get the cl at 8 deegree aoa
(which i have set through boundary conditions ) at a e.t.c 1.004*10-2 which ofc is extremely low. My domain is water. I have attached pictures of the mesh. I have done the same analysis at a 2d hydrofoil naca0012 and the results were something like 0.6, 0.8 which were ok according to papers. I have used standard k-epsilon.

My question is if the problem is in DM in MESH or in FLUENT Setup.

Thanks very much in advance

(if you need other pictures i can provide them )
