Piezoelectric electric using ANSYS mechanical workbench

  Hi,
  I'm trying to simulate a PZT using ANSYS mechanical workbench.
  I have downloaded the ACT successfully. Now I am trying to duplicate the results for the “Piezoelectric fan” found in the documentation, but I failed. I am stuck for a long time and I do not know what I am doing wrong?!!!
  For Example:
  In the modal analysis, the answer is [Mode1 = 60.142 HZ, Mode2 = 349.28 HZ]. For me, I get [Mode1 = 59.949 HZ, Mode2 = 333.12 Hz]
  Further, for the frequency response, I get a completely different plot than the one in the documentation and have no idea why !!!!
  
  Note: I am using ANSYS 2020
  
  Any help will be appreciated

  Hi
  
  THe act extension is not supported and developed longer.
  
  Use the coupled field modal and harmonic to analyse Piezoelectric+structure+acoustics (if needed).
  For an example see technology demo or showcase TD39: Wire Bonding with Ultrasonic Transducer
  All the best

  Thank you for your reply
  My goal was to solve the piezoelectric in an FSI problem (FlUENT+ Transient Structure). So, I had first to validate an ANSYS problem (Modal + Harmonic).
  To be on the same page, do you mean this video where he is using the ACT (Piezo & Mems):

  or am I wrong ?!
  Thank you

  It is perhaps the same or similar model – but what I refer to is td39 in the help manual (search for that title in the ansys help manual: Wire Bonding with Ultrasonic Transducer) and using the native coupled field system – as we said the act mems is not supported anymore by us.
  
  All the best

  Oh, I see that now
  Thank you, that is really helpful.

  can we use a Coupled Field Transient (Piezoelectric with transient structure) in system coupling with FLUENT?!!!
  I am trying to do that but I keep getting errors, the coupling is not working!!

  Hi
  It is there and possible to use from 2023 R1.
  See the 2023 R1 help manual under the system coupling user guid and section:
  Supported Coupling Participants for System Coupling in Workbench
  
  All the best
