HI,does anybody find a variance that the lift(drag) value we back-calculated by the lift(drag) curve sometimes isn't the same as that Fluent reports (Reprot\Forces).

after the calculation when using the report forces panel you shoul use the right vector directions in X and Y coordinates. if your flow has an angle with the body these value must not be eg X=1 Y=0 for drag. you should input them aligned with the flow direction
