Hi, <\/p>\n

I am running the LES+FW-H model to siumulate noise generated in the pipe.<\/p>\n

<\/p>\n

Wall is the outer surface of the fluid domain. My question is that, in the simulation, there is no solid of the pipe, only the fluid domain, should I include the wall in the sound source?<\/p>\n

 <\/p>\n

Another question:<\/p>\n

My model is show in the plot as followed:<\/p>\n

<\/p>\n

 I want to only export the noise generated in the small protrusion part. How can I achieve that. <\/p>\n

I am using the discovery and fluent mesh to generate the mesh file. And i seperate that part in the discovery as a zone. But I cannot choose that zone in the source zone area<\/p>\n
