Abaqus 
Hello everyone,

I'm currently working on an acoustic analysis project using Abaqus, and I need some clarification regarding the calculation of the RADPOW output variable. According to the Abaqus documentation, RADPOW is described as the radiated power from/into a given acoustic cavity through the specified boundary.

However, I couldn’t find any specific formula or detailed explanation in the manual about how RADPOW is actually calculated. Does anyone know if there is a specific formula used by Abaqus to compute RADPOW? Any references or insights into the underlying method would be extremely helpful.

Thanks in advance for your assistance!
