hi everybody,I have a problem in Fluent initialazation

my case is a 3d multielement wing in a low speed contion, SA model,the grid is about 3m cells

to calculate the lift and drag of wings at high angles of attack, say 30 degrees, I can either initialized my case at inlet boundary, that is 30 degrees, to iterarte, or change the boundary condtions at the converged 25 angle of attack case and then iterate, the result, as is thought, should be the same, since the governing equations and boundary condtion are the same

However, the true result is not the same ,the formor result showed that the wing is stalled, and latter results show the air is still attached

So which result should i believe?
