Finite-difference time-domain (FDTD) wave propagation modeling in lossless acoustic 2D media.

 
Synopsis
        sfawefd2d_fo < Fwav.rsf vel=Fvel.rsf den=Fden.rsf sou=Fsou.rsf rec=Frec.rsf > Fdat.rsf datvz=Fdatvz.rsf wfl=Fwfl.rsf verb=n snap=n free=n expl=n dabc=n recvz=n srctype=1 jdata=1 jsnap=nt nqz=sf_n(az) nqx=sf_n(ax) oqz=sf_o(az) oqx=sf_o(ax)

This program fdelmodc can be used to model waves conforming the 2D wave equation in different media.
This program computes a solution of the 2D acoustic wave equation
defined through the first-order linearized systems of Newton's and Hooke's law.
