Abstract: A method of performing structural analysis relating to a component (18) having CAD-based geometry (200), refined CAD-based geometry and CAD-based FEA data (60) associated therewith. The method includes scanning (72) the component to obtain scan-based point cloud geometry of the component, aligning the scan-based point cloud geometry with the CAD-based geometry (200) of the component (18), generating scan-based geometry of the component by refining the scan-based point cloud geometry, comparing the scan-based geometry with the refined CAD-based geometry of the component (18) to quantify geometric differences therebetween, generating scan-based FEA geometry (250) of the component (18) by meshing the scan-based geometry, performing finite element analysis on the scan-based FEA geometry (250) to obtain scan-based FEA data and comparing the scan-based FEA data with the CAD-based FEA data (170) of the component (18) to quantify the effect of geometric difference therebetween.
