Hello,
I am simulating rayleigh surface waves with the structural mechanics module in time domain but cannot get rid of the wave reflections at the boundary next to the surface. I tried of course infinite domains, but the performance was pretty bad even for a simple Pwave example that I tested. Therefore, I tried low-reflecting boundary conditions, also with user defined rayleigh surface wave speed for this boundary condition. This works much better than infinite domains but the reflection makes my data not meaningful as it is still relatively large.
My question: Has anybody experience with simulating elastic waves in solids and getting rid of reflections? How should one choose the parameter(s) for infinite domains?
This is a very obvious problem but I could not find any information to get a satisfying solution.
Thank you so much for your time and help!
Best regards, Merlin.
