Hi all,

I'm practicing to replicate the model of a paper which is attached, and now I trying to model the FIG.3 (b).

I'm wondering that how can I specify a "phase boundary condition" on the boundary, I can't find it on the boundary condition list.

Thank you in advanced.

I can't spend the time to read this paper. However, in pressure acoustics frequency domain you can apply a pressure BC, which can be complex, so it can contain phase information. Not sure if this is what you want.

Cheers Edgar

Thank you very much, I'll try it. :)
