1. Introduction
    This package is used for simulating wave propagation in 2D complex isotropic
    media by using staggered or Lebedev finite difference method.
    We use different effective media parameterization method to generate grid model
    from layered model, then we use staggered or Lebedev FD scheme to calculate
    velocity-stress equation.

3 Usage

  1) Compile: make

  2) change the ./DATA/Par_file, add ./DATA/STATIONS if needed, add interface and
        material file if needed;

  3) run: run_lebedev.sh
        # Temporary for Lebedev test

  4) cd OUTPUT/ file for your results
     or you can cd mfiles/plot_* to plot the wavefields or seismo
