I first used Aggregate Mass in ADAMS to calculate SNL 13.2MW mass moment of inertia and I used the outputs into .bmi file. The results of N.F are quite off from what I got from ADAMS (with only Twr DoFs on).
I specified a rigid NRELOffshrBsline5MW_Monopile_RF with all DoFs turning off since I only want to see the mass moment of inertia.
I used FAST 2012Feb edition I believe and thus I delete the line added in the new FAST this year.
I generated ADAMS model and get the mass inertia properties as following:
The aggregate mass in the global reference frame is:
Mass : 3.500003109E+005 kg
Center of Mass :
Location : -0.4106407744, -2.3123880885E-009, 109.5667156223 (meter, meter, meter)
Orientation : 89.9989498566, 5.3861985327, 270.0010456486 (deg)
Mass Inertia Tensor :
IXX : 4.2454591844E+009 kg-meter2
IYY : 4.2253361673E+009 kg-meter2
IZZ : 2.5520945258E+007 kg-meter2
IXY : 0.2290994561 kg-meter2
IZX : -1.4007405804E+007 kg-meter2
IYZ : 2.8746322068 kg-meter2
which I updated your .bmi, the results are quite off again.
Please help me to check I am doing the right thing.
