Hello,

I am trying to do acoustic modeling in Abaqus which was previously done in COMSOL. I am attaching the input and properties of that modeling for your concern. I am struggling with the boundary condition where I have created an amplitude following this equation. But couldn't figure out how I can implement the conditions in the inlet, interface and outlet boundary. Again, I am confused about the Pressure wave velocity and Shear wave velocity provided here. Where should I use those velocities? Please response. Thank you for your support.
