Acoustic simulation : CAABSF/PAASF assignment
Hello,
I have modelled air around the housing. These structural and fluids are coupled by ACMODL Card. I want to define non-reflecting boundary. for that I have defined PAABSF and referenced to CAABSF. But I dont know how to assign CAABSF to Elements.
Thanks in advance.

Thanks Rahul for your Reply.
But I get some different options.

set type of element config as quad4 then second option contain will give CAABSF.
Okay, I found it Rahul.
Thanks a lot.

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.

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