Hi Sarah,

Acoustic module for Fluent is Ffoct William Hawkin model. You can choose the model from Define/Model/Acoustic but, the simulation should be unsteady problem (the simulation parameter should be satisfied by stability condition) And, the version of Fluent should be 6.1 or newer version. For any question, please feel free to ask me at
