It is difficult to determine which settings should be used, whether steady or transient and what is the significance of calculating performance curve after airofoil stalls ?? I would recommend going through the courses available on AIS. What I gather from your statement is that you entered AOA values manually. Please do check the parametric option in Ansys Fluent to generate a set of output parameters based on the input parameters(if interested).
