Notice that kwave can simulate elastic wave, wondering it is feasible to simulate Rayleigh wave or Lamb wave these type of more complicated wave modes? Thanks in advance.

A MATLAB toolbox for the timedomain
simulation of acoustic wave fields
Can kwave simulate Rayleigh wave propagating on the surface of a large block?

Hi ncsuligang,
We have never tested this explicitly, although I don't see any reason why they would not be included in the model. For example, Virieux shows this kind of behaviour solving an equivalent set of governing equations using the finite difference method.
Hope that helps,
Brad.

Dear Brad,
Does this mean that the existing functions such as pstdElastic2D can do that or does it require modification in the code to introduce new set of equations?
Best,

Hi umitarabul,
The existing codes can capture Rayleigh waves and the various other elastic wave modes (we have now tested this against the global matrix method for layered materials).

Dear Brad,
Can you give some short insight how to configure kwave so that Rayleigh waves are correctly modelled?

Hi scorprulebad,
What exactly are you having trouble with? It's all built into the governing equations, so there's nothing in particular that you need to do. However, in general, I'd definitely advise running a convergence test (decrease the grid spacing until the answer stops changing).
Brad.
