SPECFEM

Hi, this is the SPECFEM github organization site to host a family of spectral-element code repositories.

We are dedicated to open-source development for the computational seismology community. If you want to follow and participate in the discussions on this site, here is a quick setup guide for you

Pinned Loading

specfem1d specfem1d Public

SPECFEM1D simulates seismic wave propagation in a one-dimensional heterogeneous medium. It is a small code that allows users to learn how a spectral-element program is written.

Fortran 22 32
specfem2d specfem2d Public

SPECFEM2D simulates forward and adjoint seismic wave propagation in two-dimensional acoustic, (an)elastic, poroelastic or coupled acoustic-(an)elastic-poroelastic media, with Convolution PML absorb…

C 253 165
specfem3d specfem3d Public

SPECFEM3D Cartesian simulates acoustic (fluid), elastic (solid), coupled acoustic/elastic, or poroelastic seismic wave propagation in any type of conforming mesh of hexahedra (structured & unstruct…

Fortran 512 258
specfem3d_globe specfem3d_globe Public

SPECFEM3D Globe simulates global and regional (continental-scale) seismic wave propagation for Earth, Mars & Moon.

Fortran 114 100
shakemovie shakemovie Public

A visualization tool to render ShakeMovie visualizations

C 4 1
specfem3d_geotech specfem3d_geotech Public

SPECFEM3D_GEOTECH is an open-source command-driven software for 3D slope stability analysis and simulation of 3D multistage excavation based on the spectral-element method.

Fortran 40 16
