How can I extract real and imaginary equivalent stress parts in a cyclic symmetry analysis?

I'd like to get an array of the SEQV values I get from PRNSOL,S,PRIN or /CYCPHASE,LIST after doing a stress phase sweep. I've tried using *VGET or *GET in a loop to retrieve the nodal values but MAPDL warns that the values are unprocessed (meaning not expanded). I've tried calculating SEQV from the base and duplicate nodal values using the response equation shown in Section 3.4.2 of the MAPDL help but the values only match for a 0 phase angle.

    You should never combine the invariant stresses directly. You combine the components and then recalculate the invariants from the components.

    Hi @fsalmon What version are you using? Can you post both the SET and /CYCEXPAND commands that were issued prior to listing of results. Or better yet, I don't suppose you have a small test model that you can share?
