I am modeling sound through a passageway of bone with the hope of getting a vibration respones from the bone structure. To do this I have linked a full harmonic acoustic analysis to a harmonic response analysis. Online I have seen mention of including a Fluid Structure Interaction component but try as I might I cannot find this component in Workbench. Is this necessary? If so, could it be that my license does not permit it?

Hi

 

’To do this I have linked a full harmonic acoustic analysis to a harmonic response analysis.'

Answer: You can not do this.

Only the other way around is possible so harmonic response analysis -> harmonic acoustic (say looking at sound radiation from a vibrating speaker cone).

Also harmonic acoustics relates to pressure acoustic waves in gases/fluids and not in structures - in structures the wave propagation is different and more complex (bulk and shear waves so P and S waves).

There are many acoustic courses that discuss this and I would recommend taking (also book from Achenbach and Graff are good here).

For using acoustic analysis in Ansys:

See our course in acoustics : Topics in Acoustic Analysis | Ansys Innovation Courses

Many tutorials online also.

All the best

Thank you for the quick response. 

So, instead do I need to model this using a one-way FSI with a Fluid FLow (Fuent) connected to a Transient Structural?
