I need to work on one of the acoustic modules of ANSYS that my task is importing (Displacement) data "Output of Transient Structural Module" in to the Acoustic module and Calculate the pressure (Acoustic Wave) as the Ultrasound idea. I NEED to Know:
1- Which module should i use Model Acoustic or Harmonic Acoustics?
2- Should i define a physical region or not ? "N.B.: I don't know what's the meaning of physical region in acoustics"
Also i have downloaded the ACT and Acoustics Extension; installed them on ANSYS Workbench but still can't work on any of the acoustic modules, there's a (?) beside the module as shown in figure, WHY???
Help Please... Thanks in advance
