I am a little confused because I want to work in this area using FE in 3D models. My questions are:
a) does anyone know if there are some reasons for not employing FE to simulate ultrasound propagation (e.g. inability of FE to model such problems, more disadvantages than advantages. etc.)?
b) Are there more papers in the literature than I have found?
c) Ultrasound excitation (in contact application) should be regarded as a force boundary condition or prescribed displacement at the transducer/medium interface (my opinion is the former case).
Thank you very much, in advance, for your feedback.
