Acoustic Infinite elements CAE

Acoustic Infinite elements CAE

Acoustic Infinite elements CAE

(OP)
Hello everyone!

I am trying to assign acoustic infinite elements using CAE (I have a model with predifined node and element numbering without a sequence in numbering so it is very diffcult to create the elements in the input file).

The manual descripes how to do this, but I am failing to succeed it. The acousitc elements lokk like with "surface" elements so
there should be no part or elements to assign the section. As I am trying to assign the section to normal parts, it is not choseable
as it is not available fot such "normal parts".

Could anyone give me hints how could I model acoustic infinite elements with CAE (please no the manual instructions).

Thank you very much in advance!
Georgios
