  Hi, nIn earlier Ansys fluent fw-h acoustic model, I used to get the dpdt RMS values after acoustic post processing. This was about 5-6 years ago. But in recent versions, after running the fwh model and after read-compute-write, I always get dpdt RMS values =zero at all surfaces. Could you please check why this is, and advice how to obtain dpdt RMS at acoustic surfaces.nThank you nSaha

  Hello,nAre those surfaces you are reporting dpdt RMS on walls or permeable? Note that RMS value of the static pressure time derivative is available for postprocessing only on wall surfaces.n
