摘要

•Shapes in STEP format are morphed by controlling user-defined handles.•Re-meshing is avoided by mesh adaptation to shape variations.•Differentiated to support adjoint-based optimizations.•Sequential combination of many morphing steps.•Assessed in gradient-free and gradient-based aerodynamic shape optimizations.
