Greetings,
I am pleased to announce the release of PyLith 2.0.3, a finite-element
code designed to solve dynamic elastic problems and quasi-static
viscoelastic problems in tectonic deformation.
This release provides several small updates for (1) improved
CUBIT/Trelis compatibility in example journal files, (2) building with
recent versions of automake, and (3) additional examples from the 2014
Crustal Deformation Modeling Workshop tutorials.
You can download the source code and binaries from
http://geodynamics.org/cig/software/pylith
Detailed installation instructions for the binary packages are in the
User Manual with detailed building instructions for a few platforms in
the INSTALL file bundled with the PyLith Installer utility.

MIGRATING FROM VERSION 1.9 TO 2.0
======================================================================
Changes to various C++ objects permitted simplifying the specification
of a number of components. The map below indicates the name changes.
CellFilterAvgMesh -> CellFilterAvg
DataWriterVTKMesh -> DataWriterVTK
DataWriterVTKSubMesh -> DataWriterVTK
DataWriterVTKSubSubMesh -> DataWriterVTK
DataWriterHDF5Mesh -> DataWriterHDF5
DataWriterHDF5SubMesh -> DataWriterHDF5
DataWriterHDF5SubSubMesh -> DataWriterHDF5
DataWriterHDF5ExtMesh -> DataWriterHDF5Ext
DataWriterHDF5ExtSubMesh -> DataWriterHDF5Ext
DataWriterHDF5ExtSubSubMesh -> DataWriterHDF5Ext
Running the script:
bash $PYLITH_DIR/doc/developer/update_1.9to2.0.sh
will update all .cfg files in the current directory and all
subdirectories with the new names (you will need to replace
$PYLITH_DIR with the directory containing the PyLith source code).
PyLith allows use of the Chaco and ParMetis/Metis partitioners. The
name of the ParMetis/Metis partitioner was changed from "parmetis" to
"metis".
[pylithapp.mesh_generator]
distributor.partitioner = metis
Buried edges of faults are handled differently in v2.0. A separate
nodeset/pset should be created and contain the vertices on the buried
edges of the fault. See the Section 6.4.2 of the PyLith manual for
more information.

RELEASE NOTES
======================================================================
----------------------------------------------------------------------
Version 2.0.3
----------------------------------------------------------------------
* Bug fixes
- Updated autotools files (Makefile.am, configure.ac) for
compatibility with recent versions of automake (up to and including
v1.14.1).
----------------------------------------------------------------------
Version 2.0.2
----------------------------------------------------------------------
* Bug fixes
- Fixed linking issue in Darwin binary distribution, primarily
affecting systems with OS X 10.7 and 10.8.
- Improved example journal files for CUBIT/Trelis to improve
compability (examples/meshing/surface_nurbs/dem).
- Updated more journal in examples so that APREPRO lines have a
leading '$' instead of a '#' to differentiate from comments.
- Added examples/debugging files from Crustal Deformation Modeling
workshop debugging tutorial.
----------------------------------------------------------------------
Version 2.0.1
----------------------------------------------------------------------
* Added example (examples/2d/gravity) for viscoelastic deformation in
2-D with gravitational body forces and small strain formulation.
* Bug fixes
- Improved example journal files for CUBIT/Trelis to improve
compability. All journal files should work with CUBIT 14.1 and
Trelis 15.0.
- Created examples of IDless journal files in examples/2d/greensfns.
These files should work with all recent versions of CUBIT and
Trelis.
- Switched journal APREPRO lines to have leading '$' instead of '#'
to differentiate from comments.
