Acoustic simulation
 
Hi everyone,

When I ran a "fan" project, I set Ffowcs-Williams_Hawkings model to compute acoustic noise. Convergence was fine, but when I read & compute acoustic signal, there was an error message :

Error: Read_Next_Acoustic_Timestep: Opening paranthesis I in file (file_name)-noise_500.asd

Error Object: ()

Then, I tried to iterate more. There was another error message:

Error: Floating point error: invalid number

Error Object: ()

After I set Acoustic model ---> off, then the iteration could continue!

Has anyone met this condition? If you know how to solve this, please kindly response to me.

Thanks lots.
