Hello, I meet a problem in Harmonic Acoustic in ANSYS 2020R1. It is prefect that the software support three usually acoustic coefficients, such as transmission, absorption and return coefficients. I want to test an object’s acoustic characteristics in a pipe, which includes the three coefficients mentioned above. But I don’t know how to set up the PORT correctly. Maybe I didn’t get the understanding of the PORT. And my process is written as below, and hopefully anyone could give me some suggestions.
It is a pipe. Since it is needed to create interface which can be used to define as the face of acoustic coefficients, I divide it into two part sharing the topology. The position is shown as the body color varies. The setting of PORT are shown as the Figure 2, in which the red means the face and blue means the geometry. But as expected, it didn’t work and the question may occur at the setting of PORT. I will be gratefully if anyone could give me a hand.
Figure 1. The interface
Figure 2. PORT description
BTW, if I want to perform the planar wave into the pipe, should I use incident wave sources or port in duct? Once I choose option incident wave sources, the planar wave is locked outside the geometry. On the other hand, the option port in duct, I cannot configure it right. So I reaaaaaally want to know, what is the definition of PORT and how will work in the program.

Or Anyone can send some tutorials or projects which is configure correctly,
Thanks a lot!!!!!!!!!
