Hello everyone. First, a displacement of 2 mm is applied to the reference point, and then a sine-sweep excitation with an amplitude of 1 mm is applied on the basis of this displacement. However, displacements between analysis step cannot be superimposed. How to use direct-solution steady-state dynamic analysis for frequency response analysis in this case? How to make the displacements between different analysis steps stack up?
