PyLith

The latest release (version 1.5.1 in source code and binaries) allows the solution of both quasi-static and dynamic problems in one, two, or three dimensions. PyLith 1.0 was a complete rewrite of the original PyLith 0.8. 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 1.5 provides several new features and enhancements. New features include dynamic fault interfaces using fault constitutive models, a Drucker-Prager elastoplastic 3D bulk rheology, a lumped system Jacobian formulation for explicit time stepping, and a total Lagrangian small strain elasticity formulation. Enhancements include scientific notation for ASCII VTK files, use of CUBIT nodeset names, and output of velocity fields. The manual has also been updated for the new features and includes more examples.

Version 1.5.1 fixes a couple of bugs. See the release announcement for details. We strongly recommend that all users update to this current release.

Current Release

Source Code

pylith-1.5.1.tgz [2010-07-20]

Version 1.5.1

spatialdata-0.6.0.tgz [2010-06-11]

Spatialdata is required for PyLith v1.x. Spatialdata provides transformations among coordinate systems and simple databases for specification of boundary conditions and material properties. Version 0.5.2 does not require SWIG when configuring.

petsc-dev-pylith-1.5.1.tgz [2010-07-20]

PyLith 1.5.x requires the development version of PETSc at the time of the PyLith 1.5.x release. PETSc provides finite-element mesh data structures (Sieve) and parallel linear algebra routines and data structures. This source distribution works for release 1.5.1.

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.

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.
