Acoustic simulation : CAABSF/PAASF assignment

The CAABSF element must connect entirely to fluid points on the fluid-structure boundary. Card edit option would help you to assign CAABSF eleements

Thanks Rahul for your Reply.

But I get some different options. 

<?xml version="1.0" encoding="UTF-8"?>

set  type of element config as quad4 then second option contain will give CAABSF.

Okay, I found it Rahul. 
Thanks a lot.

Instead applying only on the fluid structure boundary, I have kept elem type as a CAABSF on all fluid Elements. 
Is that fine?

Hi, Rahul, 

I am done with modelling of the fluid structural coupling Problem. 
I have attached file. could you please check it once.

Bauteil1,2 and platte - structural components
Air - fluid (At the end non reflecting boundary)

Please check if PAABSF and CAABSF are correctly defined or not.

Thanks a lot.

Regards,

Vikrant
