Reply To: Ansys Acoustics – Connect Coupled Field Modal to Response Spectrum

[Erik Kostson]

 

 

Hi

As you found out you can not link the two. Response Spectrum links only to pure structural Modal Analysis system only (see here: https://simutechgroup.com/apdl-commands-objects-mechanical-after-response-spectrum-analysis/)

(So Response Spectrum can not be linked to coupled field modal and modal acoustic systems).

In general we can not do any mode super position harmonic and response spectrum in Workbench when an acoustic region is present.

This is documented and explained in the help manual.

All the best

Erik
