I noted in the Boeing CFD modelling, they do not consider the center wing area for lift, so it appears they do not model the nacelles for lift either.
Might this be why the software fix was 0.6 degrees but in flight test, it was actually 2.5 degrees?
Airbus does use the center wing lift area in their models, but I dont know about engine nacelle.
