Hi Borzki,

Thank you for your advise,

I want to clarify which frequency shall be considered to pick up displacement output to compare with measured data?

For example, the exciting freq is 7.3Hz, since the harmonic analysis will sweep through a range of freq and resonance may not be at 7.3Hz but let's say at 7.5Hz. My understanding is the adjustment is trying to let displacement output at 7.3Hz is same with measured data rather than 7.5Hz. Since there is big different of diplacement output from these two freq (disp at 7.5Hz > disp at 7.3Hz)
