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
