 The Aerodynamics 3D v1 configuration requires the complete obstacle to remain inside the
 Cartesian periodic box; configurations whose geometry crosses an x, y, or z boundary are
 rejected. Results retain only `u`, `v`, `w`, and pressure volumetric histories. Derived slice
 histories and streamline polylines are prepared lazily in the Results window and are not added
 to the solver result object.
