  Hi,
  I'm quite new to ANSYS so I'm not sure if this is an issue with my model but I suspect its an error in the extension.
  I'm using ANSYS workbench 17.1 and I downloaded the acoustics extension (link below), so that I could use the harmonic acoustics analysis:

  Hi Alicia, what material properties did you assign to the acoustic body under engineering data?n

  Hi HuiLiu,nIt's the built-in values for air for ANSYS, so just density (=1.225 kg/m^3). The error message says I'm missing elastic data for the material, which is why I'm assuming it thinks the air domain is a solid body/ non-acoustic body.n
