Hello everyone,
I have a little problem with definition of FFD boxes. I am doing an aerodynamic optimization of the BWB using multiple FFD boxes. I have successfully built them, but, when I am running the solution, the code gives me an error and says that my DV dimensions do not agree. I checked them again but they were fine. Could you tell me where my little mistake is? I have attached the run file. Thank you, Stan the error message: --------- Start gradient evaluation using sensitivity information ---------- Evaluate functional gradient using Algorithmic Differentiation (ZONE 0). 4 Free Form Deformation boxes. 1 Free Form Deformation nested levels. FFD box tag: WINGINNER1. FFD box level: 0. Degrees: 10, 2, 1. FFD Blending using Bezier Curves. Number of parent boxes: 0. Number of child boxes: 0. Corner points: 8. Control points: 66.
