New approach for accurate, robust morphing of CAD geometries

Facilitates bi-di transfer between analysis-testmanufacture and design

ABSTRACT

Connecting simulation and test results into the design process, such that analysis truly leads design, offers potentially significant breakthroughs for manufacturers.

This technical article describes a new, automated approach to accurately and robustly morph CAD geometry based on results of analysis in order to facilitate the missing bi-directional transfer of these geometries between analysis/test/manufacture and design.
Two industrial examples using this approach are also provided, in the morphing of a turbine blade deformation model and aero-elastic deformation of aerodynamic shapes for the NASA Common Research Model. This technique is particularly useful for cases requiring multi-disciplinary analysis and automatic shape optimization for further, independent CAE analysis.
