I understand what you are telling me. However, as I said before, the amplification shown is dimensionless since it divides one acceleration value by another. As far as I know, you have to divide the values obtained at a point of the structure by the values obtained at the base.
Amplification factor = values of the point of interest / values of the reference point
In the cases in which this test is carried out with a vibrating table, this last value (reference point) is taken from an accelerometer located on the table where the structure is anchored. However, if I take as a reference point a node of the model that is anchored to the ground, the values of the acceleration of that node will be equal to 0 (or almost 0), making the result of the division not suitable.
Any ideas on how to do it properly in Ansys?
