[CIG-SEISMO] Few questions on SW4 (Lukáš Janků)

Hi Lukas,
The sw4 source code distribution contains a directory called examples,
where several different wave propagation problems are solved. A couple of
them include realistic topography, such as examples/pfiles/Caucasus.in. In
this case, the topography is given on a lat-lon grid in the file
caucasus.topo. To get started I recommend running this case and reading
the chapter on topography in the user's guide.
We might make a webinar in the future, but for now your best bet is going
through the examples and studying at the user's guide.
Let me know if you have any further questions,
Anders
