Solving the Convective Wave Equation for the Mean Flow Effect


Im trying to perform transmisson loss in the muffler with mean flow effect.

I ve performed harmonic acoustic and i have followed mechanical apdl help 11.3.

the analisys:

the errors:

the wornings:

can you help me ?

thanks a lot

    Does the model run if you don't apply mean flow effect? There is warning message regarding FSI interface, do you have merged nodes (ie. share topology on) between your structural and fluid domains?
