Running Demo3 clearly shows surface Rayleigh waves on the vertical component for a P-wave source with a depth of sz=20.

All:

A slight correction to the directory where I found my FD demos is “cwp/src/demos/Synthetic/Finite_Difference/Suea2df”. Presumably these demos show elastic anisotropic 2D models and the finite-difference synthetics.

Hello Dominique:

Hmm, that’s odd. Of the few Demos I looked at last night, the models were anisotropic and I could see the surface waves on the images. I haven’t had time to dig into the scripts that generated these Demos so I can’t give you more details.

Best regards,

Jim Gaiser

Hi, no.

it's acoustic and you need S waves to generate surface waves...

Hello Paul:

Do the scripts and codes in “./src/demos/Synthetic/Finite_Difference” model surface waves? I haven’t checked.

Hello colleagues.

In Seismic Unix, there are packages for elastic modeling (trielas, suea2df). I would like to know if there is a way to model surface waves (or ground roll) in seismic UNIX. Or do you know some other package free-open source?

thanks very much.

Sincerely,

Paul Goyes

Dear Dominique, Thanks for that important reminder. Do we have an idea of how often the wiki gets used? Best, Juan

Hi, Sorry, I did'nt know sued2df !!!

By the way, just a remainder to all su users that we need demos/tutorials  at wiki.seismic-unix.org to attract new users...
