Hi,

I have a speaker in a hemispherical surrounding. I want to know the pressure at 1 meter from this sphere. At the moment i am searching for nodes which are at about 1 meter from the speaker and then i extract the pressure from those. Is there a better way? I thought about using postint but don't know how to implement this.

Thanks in advance,

AM

Hi

I usually make an interiour boundary (by adding a sphere I expect in your case) where I want to measure/postprocess some properties,

You have also specific line integration across the volume, but I beleive its limited to lines, not circles ?

Good luck
