Paul:

I am new to this SU mailing list so I am not sure you are getting my responses.

Look at the demos in “cwp/src/demos/Synthetic/Finite_Difference/Suea2df”, specifically Demo3. It creates a Rayleigh wave because the source sz is only 20. I know nothing about the accuracy or limitations of this code but It is a place to start.

Hope this helps,

Jim Gaiser

Subject: [Seisunix] Surface wave modeling in seismic unix

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
