  Hi, I'm trying to do a DDAM on Ansys 19.2 (Modal), the code that I use is based in the one showed in this page, in the point 6.7.3, with some irrelevant modifications. That code worked on version 14 of Ansys, but now, in 19.2 and even in 19.0, doesn't work. If I open the Solution Information (Worksheet) of one analysis made with the version 14 and i compare it with the one of the version 19.2, the only difference is that in the new version, it shows the next error: "No data relative to modal analysis on MODE file. Existing data is coming from spectrum analysis. *GET command failed" and the execution ends there, while in the old version were made more calculations from that point. If you don't know what's wrong with that code, do you know any other way of performing a DDAM analysis on Ansys 19.2?
  
  Sorry if i did not explain myself so good, but this world is a bit new for me. Thanks!

  Please see the version 19.2 of the Mechanical APDL help. There were some changes to DDAM so you need the correct procedure.
