The latest release (version 1.1.2 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 1.1 adds a number of new features, including Neumann (traction) boundary conditions, absorbing boundary conditions, Dirichlet boundary conditions with displacement and/or velocity values, a generalized Maxwell viscoelastic bulk constitutive model, and output of fault and material information (state variables and diagnostic information). We have also added a number of consistency checks to trap and report errors in the input parameters. The manual has been updated to reflect the new features and also includes detailed installation instructions for building from source.

Beta Release

Release 1.2.0 beta adds multiple kinematic earthquake sources and gravitational body forces.

spatialdata-0.3.1.tgz [2008-06-06]

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 0.3.1 eliminates clobbering of source files in "make clean".

pyrexembed-1.0.tgz [2007-12-05]

Pyrexembed is required for PyLith v1.x. Pyrexembed is a CIG customized version of Pyrexembed that provides Python bindings for C++ code.

petsc-dev-pylith_1_1_2.tgz [2008-05-11]

PyLith 1.1.x requires the development version of PETSc at the time of the PyLith 1.1.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.
