The latest release (version 1.4.0 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 1.4.0 provides several new features and enhancements. New features include a power-law viscoelastic rheology for 3-D problems, use of PETSc's nonlinear solvers, and time-dependent point force boundary conditions. Enhancements include a general time-dependent implementation for Dirichlet (prescribed displacement and/or velocity) boundary conditions, time-dependent Neumann boundary conditions, complete support for automatic unit conversion and nondimensionalization, use of a symmetric sparse matrix, and use of SWIG for Python/C++ interaction. The manual has also been updated for the new features and revised based on feedback from users.

Current Release

Source Code

pylith-1.4.0.tgz [2009-07-01]

Version 1.4.0

spatialdata-0.5.1.tgz [2009-07-01]

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 0.5.1 correctly traps errors when parsing units.

petsc-dev-pylith-1.4.0.tgz [2009-07-01]

PyLith 1.4.x requires the development version of PETSc at the time of the PyLith 1.4.x release. PETSc provides finite-element mesh data structures (Sieve) and parallel linear algebra routines and data structures.

nemesis-1.0.tar.gz [2007-07-01]

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.
