Hello everyone. <\/p>\n

 <\/p>\n

I want to perform an modal simulation to extract the modes using only the panel, then the acoustic cavity and then the system panel+ acoustic cavity.<\/p>\n

After, I want to perform an harmonic analysis to extract the sound pressure level generated in the system panel + acoustic cavity.<\/p>\n

My main goal is to extract the sound level pressure, but I’m a little bit ansure about the process. <\/p>\n

I try using the harmonic acoustic, but i’m get 2 error messages. <\/p>\n

1 – 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. <\/p>\n

2 – An error occurred inside the POST PROCESSING module. <\/p>\n

If someone would like to see the project, i would send it.  <\/p>\n
