Kvothe332 is on a distinguished road
I am doing simulations on a 3d wing with every option verified and i am doing it steady state. I am doing different AOA. AOA 0,2,6,10,14 specifically. Problem is that i didnt change anything in the mesh or the options and first 3 AOA (0,2,6) were fine and ran for the whole time without any issue. But with 10 and 14 degree, fluent starts to give the warnings like "absolute pressure limited to", "temperature limited to", "time step reduced to excessive temp change" and starts to give wrong values. I dont know whats happening here as first 3 AOA were fine with correct results (verified with experimental).

Please give me your opinion. Thank you
