Hi mji,nThank you very much for your comment!n I checked the solver output file admodel.prt for the analysis with mass scaling turned on. I found this data from the file (the unit of mass is milligrams):nThe highlighted row corresponds to the phone part. I guess these are the correct values for the mass scaling that I should use when checking how much the mass scaling affected to the mass of each part.nHowever, I'm a little bit confused now what do those MASSALL results mean that I showed in the first message, especially the row saying Total [kg].n-Nikken
