Hi everyone,
I'm trying to model a axisymmetric disk in 2D which is actuated with 40kHz in the middle in axial direction which gives a pressure wave in the surrounding air. The air is represented by an cylinder. I coupled the two domains by inward acceleration on the boundaries.
However how do I set prescribed displacement of the middle of the disk to be a sine wave with 40kHz and an amplitude of 0.01m? I want to study the wavefronts in the air, so I have chosen for frequency domain study.
What I did so far:
1) Prescribed displacement in Solid Mechanics, selected a point and set w0 to 0.01[m].
2)Computed a frequency domain study, but there are no pressure waves in my acoustic domain.
I also tried to set the displacement with a sine function and variable t, but that gave an error.
So how should I set the sinusoidal displacement for a correct computation of the wavefronts?
Thanks in advance for helping me!
