Big quantities in modal analysis for deformation

Big quantities in modal analysis for deformation

(OP)
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)

RE: Big quantities in modal analysis for deformation

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
