Hello, I created a finite element model of a wing in HyperMesh. An experimental modal analysis has been performed on the real model of that wing, so I know what the eigenfrequencies and the eigenvectors are. Now I want to do a system identification in HyperStudy. As a response in this study I want to retrieve the eigenvectors at some nodes from output files of the optistruct solver. Under Define Responses - Expression - File sources I can actually see for the .res output file the option to select the eigenvector at a certain node, however, I can't select for which Mode/Eigenfrequency this eigenvector is. Is there a way to select a Eigenvector as a response at a certain node AND for a certain mode? Thanks!
