Computational Fluid Dynamics methods continues to play an increasingly important role in design and validation. Some examples are conditions that cannot be tested prior to fight test. In order to rely on these methods it is essential that these methods are validated and evaluated to state-of-the-art wind tunnel test and/or in-fight data. In a previous project “Cranked-Arrow Wing Aerodynamics Project International” (CAWAPI)it was clear that all CFD methods failed to some degree in the transonic regime where shock vortex interaction phenomena was present. Detailed analysis of surface pressure distribution showed that CFD where not able replicate the correct flow field and produce acceptable results. This paper aim to map out the fight conditions for which CFD is likely to fail, and try to answer or shed light in the question why? This with the main focus on the factors that influence shock vortex interaction in the flow field.
