[FAQ]

A transfer function is simply a relationship between input and output. One can obtain a transfer vector in ANSYS Mechanical, but it would need to be done manually. Basically, the user would need to solve a harmonic response analysis based on a vibration excitation at the surface of the vibrating structure. {v} is known (input), and can then get {p} anywhere in the points of interest. However, this means that if one has 200 points on the structure ({v}) and 200 points in the acoustic domain, this leads to a big matrix that the user needs to calculate manually. (Since it’s linear, one can apply {v=1} and scale it for the known values.) Obtaining ATV manually cumbersome. The ATV method is not specific to BEM but can be used with FEA. The issue is that we don’t do this process/calculation, so all of it would need to be done manually.
