specfem2d's Introduction

SPECFEM2D

SPECFEM2D allows users to perform 2D and 2.5D (i.e., axisymmetric) simulations of acoustic, elastic, viscoelastic, and poroelastic seismic wave propagation. The package can also be used for full waveform imaging (FWI) or adjoint tomography.

Main "historical" developers: Dimitri Komatitsch and Jeroen Tromp (there are currently many more!)

Installation

Instructions on how to install and use SPECFEM2D are available in the

For a quick test, run the default example with these commands:

./configure FC=gfortran make all ./bin/xmeshfem2D ./bin/xspecfem2D

and check the output files in ./OUTPUT_FILES/
