Reply To: Sound source of LES+FW-H model

[Federico]

Hello Jingyu, 

 

In the acoustics sources page, you need to select the surfaces that should be part of the sources for your calculation. Using FW-H method, you do not need to include any solid parts in your model.

Depending on what you are interested in, if you want to select the walls of outlet2 only as part of your acoustics source, you will need to have a different face zone label. You can create named selections in Discovery and remesh your model accordingly, or you can use the Separate function in Fluent (Domain > Zones > Separate > Faces) and separate by Angle. The new zone should then be available in the list of Source zones
