Rwoolhou, do you maybe know why this could be happening? Any idea or thought could help me a lot. 

I rebuilt my model from scratch, without the axis of symmetry, meshed it differently, ran with different settings, and still I am getting very high and very wrong drag report definitions, while the drag force reports are acceptable.

I am really trying to get the definitions working since I have to run my simulation at many different design points; I set both force report and drag force definition as output parameters, but the definition is overwriting the force report value, not giving me any chances to use Design Points..
