Big quantities in modal analysis for deformation

Hi everybody

doing a modal analysis for a part of dimensions of 200 mm, when I request deformation for modal analysis results, I get some maximum values like 250, 400 in deformation results, which is somehow meaningless, specially becuase I have fixed my part ( a cyclinder) from two sides)

what are these results and why are they so big ? ( don't confuse them with natural frequency, I know that)

Hi SFTmech,

By default, Ansys scales the mode shapes to the mass matrix (see MODOPT). The mode shapes are not yet scaled.


Kind regards,
Jason
