2D Acoustic Simulations Possible

Andiiiiiii

Hello,

I want to perform 2D acoustic simulations, only acoustic pressure as DoF and no fluid-structure interaction. Furthermore, I want to simulate an open boundary, that means I need CACINF or CACPML elements. As far as I understand their description, these elements are only available as 2D elements suitable for 3D simulations. However, I want to verify my understanding and ask if 2D pressure acoustic simulations with open boundary are possible in Hypermesh?
Thanks and BR

Andreas
