I got a problem about how to apply harmonic post results 'manually' in Ansys Harmonic Response Module. I have fan blade with a tuned structure. And I followed methods which are necessary such as
-unsteady pressure mapping
-determining resonance point by inserting a campbell diagram
-applying aerodamping on structure etc.
by using APDL commands.
Yet, I guess there is a BUG (see the attachment) in the harmonic response post module when trying to show results manually such as frequency response. It doesn't work! And I guess this is happening when I use cyclic symmetric structure. It doesn't appear in the full model.
Any idea how to figure this out?

This is a known limitation in MSUP Harmonic with cyclic symmetry. Setting up cyclic symmetric MSUP Harmonic in WB requires rather involved APDL commands and most post-processing (except for modal analysis) are only available through commands objects. Therefore, you have to use command objects to plot Equivalent Stress and Frequency Response.

Thanks for your response. So, is there any other way to map unsteady pressure distribution without using APDL commands. Because I have limited knowledge about commands and try to do this manually.

I have one more question;
Is there any other way to map unsteady pressure distribution without APDL commands ??

The key here is that running cyclic symmetric MSUP harmonic requires post-processing with APDL commands, so it is not about how you map pressure distribution. You can try using Full Harmonic method which will not need APDL commands.

Thanks for the answer. I didn't realize that I asked it double times, sorry.
Have a good day,
