How to make a Frequency Response Analysis with imposed external frequency-dependent displacements

  Hi everybody!
  I'm trying of performing an FRA with external results imposed as a set of displacements bouday conditions.
  In the picture below, we have a set of frequency dependent displacements (colums) per each degrees of freedom (raws). These results come from an external MatLab analysis (but this is not relevant).
  So, I ask you how can impose these frequency-dependent displacements, into the APDL framework, in order to execute the FRA. My aim is to calculate the frequency dependent stresses observing the coloured map.
  Thanks!

  You might want to have a look at this code - https://forum.ansys.com/discussion/1157/apdl-transient-analysis-only-registering-1st-acceleration-step, its something similar.
