The answer is no. Fluent has implemented some acoustic modules in their code.

It is possible to output the noise sources from CFX solver and read it in SYSNOISE software to perform the calculations.

Hi,

Ribeiro is correct, there is a way of exporting CFX results into SYSNOISE. Talk to your local support office.

The aeroacoustic modules implemented in SYSNIOSE are not exactly based on FW-H model. Depending on your applcation, you may end up using Curle's analogy or Lowson equation.
