Question concerning the harmonic acoustics

      Hi,

      I'm currently working on a speaker and I want to perform a harmonic avoustics analysis on it. When I import the frequency from harmonic response and I choose the geometry to aply the loan on, I got a little quetion mark. I also join a screenshot of my problem.


      How can I solve this problem please ?


      Best regards

      Zeynep

      Hi

      See this video on how to do this - start by doing a simple example following this video:
      Thank you

      I have already watched that tutorial and I followed the exactsama steps. Yet, I still don't understand why it does not work.

      THat is good - try it on a simple model, say just one structural block with a force surrounded by air and then do the velocity transfer to a harmonic acoustic just as in the video.

      See if that is possible.
