I am working on a modal anaylsis with ANSYS APDL. How can I get the real part, the imaginary part and the phase angle of the nodal displacement of a given node with APDL commands?
Thank you for helping :)

are you doing a damped modal analysis? If you have a complex solution then the results file will have 2 sets of results for each natural freuqency - the real part and imaginary part. You can use the SET command to look at either one. So for example you can use the below to get the UX value at node 5 for real part of mode 1 and imaginary part of mode 1. Once you have the real and imaginary values you can calculate phase angle or amplitude.
set,1,1 ! load real part of mode 1 solution
set,1,1,,1 ! load imaginary part of solution

In the future I would suggest to post this type of question (APDL/SOlver/Post pro.) in the General Mechanical forum.
All the best
