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