After converging the adjoint and setting up the morphing region, I select “Calculate Design Change” and get the following in the TUI: > Checking adjoint setup… Done Computing the design change. All boundaries in the morphing region are fixed or have prescribed motions defined. ** The user-specified Freeform Scale Factor is not used in this calculation Observable pressure-drop has a decrease in value specified as the objective. The specification of an objective and prescribed motions on all boundaries is incompatible. ** Objectives for observables will be ignored. Even though the bounding box looks fine visually, double-check the regions extents. If the min and max values are flip-flopped, you will get this message. I.e., the max must be greater than the min for a given coordinate extent.
