The layers, in order of wave propagation, are:</p> <p>water → solid → soft tissue → solid → thin water layer → air</p> <p>I’m considering using the pstdElastic3D model for this simulation, and I’d like to know:</p> <p>Can pstdElastic3D handle a mixture of elastic and fluid media?</p> <p>Especially, can it accurately model the interface between water and air, given the large impedance mismatch and strong reflections at that boundary?</p> <p>Thanks so much for your help! </p>
