[AHF]

i am modeling NACA0015 in Fluent
in the first step i want to check Independence of the mesh.
i create a mesh and make it finer and finer but each time i make it fine, my lift and drag force become more unstable.
i modeling in Steady State condition.
Re = 100000 and use k-omega SST for turbulence.
and Y+ in under 1 ( almost near 0.01 )

it is true that is drag and lift oscillation ?

thank you
