Hello,
what is being displayed when looking at the Eigen frequencies in HyperView (Analysis: EIGRL, Solver: OptiStruct)? (Result type: Eigen Mode Mag) I.e. how should you interpret the deformation that is being displayed? Something physical or just to give a qualitative demonstration of the shape of the Eigen mode?
If I compare an OptiStruct EIGRL analysis to Abaqus Frequency Analysis, I get the same Eigen frequencies and modes but the deformation that is presented by HyperView is different when looking at the EIGRL analysis results. Abaqus shows 'displacement' and HyperView 'Eigen Mode (Mag)'. And the 'Eigen Mode (Mag)' seems to be around 300-times the Abaqus 'displacement' with my example.
Deformation factor is set to 1.0.
See the figure enclosed, where the original geometry is wireframed. I am wondering why this deformation that is displayed in HV is so large.
