"Web11 de fev. de 2010 · Just as add-on as told by others correctly to you: in a SEMODES (SOL 103) analysis displacement results are meaningless. And regarding units, the system used is correct: density in Tons/mm3, and length in mm. Simply use the trick: value of mass density in kg/m3 x 1e-12. For instance, mass density of steel = 7850e-12 = 7.85 e-9 T/mm3. " - Normal modes analysis nastran
