Harmonic Perturbation
Use the Harmonic Perturbation subnode to specify the harmonic part of nonzero prescribed displacements or rotations. This node is used if the study step is frequency response of a perturbation type.
The settings are the same as in the parent Prescribed Displacement/Rotation, Prescribed Velocity, or Prescribed Displacement/Rotation node. Only degrees of freedom selected as prescribed in the parent node can be assigned a value.
