Welcome to FDwave

The pacakage is usefult for generating the seismic waves in different types of media.

Characterstics of code:

1. 2D finite difference time domain modelling over-staggered grid.
2. It can simulate the seismic wave propagation in the elastic media.
3. It uses very efficient vectorized finite difference operator.

Content in package:

FDWAVE: This directory contains all the programs & functions related to seismic modelling.

SCRIPTS: This directory contains all the file containing commands used for the modelling. How to run the program

Documentation is provided with the code as well as available online.

Note:

The code doesnt require any special installation. However, the subroutine FDwave_initialize should be included in the beginning of scripts. Further, to avoid any (remote) possibility of confilct with other subroutines while running other codes,
