Flexwin — by Sue Kientz — last modified 2009-04-17 01:51 PM

The FLEXWIN software package automates the time-window selection problem for seismologists. It operates on pairs of observed and synthetic single component seismograms, defining windows that cover as much of a given seismogram as possible, while avoiding portions of the waveform that are dominated by noise.

The Mineos package is a 1D code that simulates synthetic seismograms in the spherical symmetric nonrotated Earth by normal mode summation.

Seismic_CPML — by admin — last modified 2008-02-01 02:46 PM

SEISMIC_CPML is a set of six Fortran90 programs that solve the 2D or 3D isotropic or anisotropic elastic wave equation using a finite-difference method with Convolutional Perfectly Matched Layer (C-PML) conditions, developed by Dimitri Komatitsch and Roland Martin from University of Pau, France.

Specfem3D — by admin — last modified 2008-01-22 04:39 PM

SPECFEM3D (formerly called SPECFEM3D_BASIN) simulates seismic wave propagation in sedimentary basins.

Specfem3D Globe — by admin — last modified 2008-01-15 12:05 PM

SPECFEM3D_GLOBE simulates global and regional (continental-scale) seismic wave propagation.

Specfem2D — by admin — last modified 2009-08-27 12:58 PM

SPECFEM2D simulates seismic wave propagation in two-dimensional acoustic, (an)elastic, poroelastic or coupled acoustic-(an)elastic-poroelastic media.

Specfem1D — by admin — last modified 2008-01-22 04:53 PM

A small code that allows users to learn how a spectral-element program is written.
