      When exporting acoustic source data for example for the Ffowcs-Williams & Hawkings method, only monopole and dipole sources are exported in ANSYS Fluent implementation. Quadrupole (e.g. volumetric) contributions are related to turbulence noise and such contributions are usually less important than monopole and dipole ones for low-Mach flows. However, users can export quadrupole sources using the following TUI command: define models acoustics export-volumetric-sources? yes Export format will be standard asd. Export format can be also CGNS with the following TUI command: define models acoustics export-volumetric-sources-cgns? yes
