Remove  the far field result– take that away and it works.

 

 

 

Like it says:

 

The program controlled far-field radiation surface detection option chosen in the analysis settings could not find any surface that are a part of absorption element/surface, impedance/radiation boundaries or artificially matched layers interface. The post processor will not be able to evaluate far field results. 

So since you do not have any of those (absoprtion, radiation bc,..) it can not do that (far field calcs.) – what you have is a plate inside a room with rigid/hard walls – that is the natural bc in acoustics when no bc are defined on a face so can not look on far field outside a room with rigid walls :).

All the best
