PyLith

The latest release (version 1.8.0 in source code and binaries) allows the solution of both quasi-static and dynamic problems in one, two, or three dimensions. The code runs in either serial or parallel mode, and the design allows for relatively easy scripting using the Python programming language. Material properties and parameters for boundary and fault conditions are specified using a spatial database, which permits easy prescription of complex spatial variations of properties and parameters. Simulation parameters are generally specified through the use of simple ASCII files or the command line.

Version 1.8 provides some new features, including additional flexibility in PETSc nonlinear solver parameters, a post-processing utility to compute earthquake slip information, computation of the stable time step for explicit time-stepping, and the ability to output the stable time step for each cell in a material. The manual has also been updated for the new features.

Version 1.8.0 fixes several bugs. We strongly recommend that all users update to this current release.

Current Release

Binaries

These binaries are suitable for use on single core/processor computers as well as multi-core or multi-processor computers. They can only be used on a single compute node of a cluster. Users wanting to run PyLith on multiple compute nodes of a cluster must build from source.

Version 1.8.0 Installer for Windows 7 and Vista 64-bit. PyLith is bundled with bare-bones cygwin.

Source Code

Use the PyLith Installer to build the current PyLith release and its dependencies from source code on UN*X operating systems. Instructions are included in the installer distribution. There is no need to download any of the tarballs other than the installer distribution.

pylith-installer.1.8.0-1.tgz[2013-01-31]

Version 1.8.0-1

Source tarballs for expert users not wanting to use the PyLith Installer.

pylith-1.8.0.tgz[2012-10-24]

Version 1.8.0

spatialdata-1.9.0.tgz[2012-10-24]

Spatialdata is required for PyLith v1.x. Spatialdata provides transformations among coordinate systems and simple databases for specification of boundary conditions and material properties.

petsc-dev-pylith-1.8.0.tgz[2012-10-24]

PyLith 1.8.x requires the development version of PETSc at the time of the PyLith 1.8.x release. PETSc provides finite-element mesh data structures (Sieve) and parallel linear algebra routines and data structures. This source distribution works for release 1.8.0.

nemesis

Nemesis is required for PyLith v1.x. Nemesis simply installs a pair of Python interpreters ('nemesis' and 'mpinemesis') which incorporate MPI and include Pythia's "_mpi" module.
