Hi, Wolfram mathgroup.
I am trying to simulate the acoustic wave propagation to different media in one dimension, but it does not work. The initial pulse starts in layer 1 and this pulse propagates to the layer 2. For this, I used the interface condition between two layers as follows: i) continuity in pressure. ii) continuity in velocity. To see how the acoustic pulse is transmitted into layer 2, I think that two acoustic wave equation should be set in each layer and be solved independently. I am not sure about this. Is there anyone who can help me, please ?
Thank you in advance.
Here is the code.
