|
| 1 | +Greetings, |
| 2 | + |
| 3 | +I am pleased to announce the release of PyLith 2.0.3, a finite-element |
| 4 | +code designed to solve dynamic elastic problems and quasi-static |
| 5 | +viscoelastic problems in tectonic deformation. |
| 6 | + |
| 7 | +This release provides several small updates for (1) improved |
| 8 | +CUBIT/Trelis compatibility, (2) building with recent versions of |
| 9 | +automake, and (3) additional examples from the 2014 Crustal |
| 10 | +Deformation Modeling Workshop tutorials. |
| 11 | + |
| 12 | +You can download the source code and binaries from |
| 13 | + |
| 14 | + http://geodynamics.org/cig/software/packages/short/pylith |
| 15 | + |
| 16 | +Detailed installation instructions for the binary packages are in the |
| 17 | +User Manual with detailed building instructions for a few platforms in |
| 18 | +the INSTALL file bundled with the PyLith Installer utility. |

| 22 | +MIGRATING FROM VERSION 1.9 TO 2.0 |
| 23 | +====================================================================== |
| 24 | + |
| 25 | +Changes to various C++ objects permitted simplifying the specification |
| 26 | +of a number of components. The map below indicates the name changes. |
| 27 | + |
| 28 | + CellFilterAvgMesh -> CellFilterAvg |
| 29 | + DataWriterVTKMesh -> DataWriterVTK |
| 30 | + DataWriterVTKSubMesh -> DataWriterVTK |
| 31 | + DataWriterVTKSubSubMesh -> DataWriterVTK |
| 32 | + DataWriterHDF5Mesh -> DataWriterHDF5 |
| 33 | + DataWriterHDF5SubMesh -> DataWriterHDF5 |
| 34 | + DataWriterHDF5SubSubMesh -> DataWriterHDF5 |
| 35 | + DataWriterHDF5ExtMesh -> DataWriterHDF5Ext |
| 36 | + DataWriterHDF5ExtSubMesh -> DataWriterHDF5Ext |
| 37 | + DataWriterHDF5ExtSubSubMesh -> DataWriterHDF5Ext |
| 38 | + |
| 39 | + Running the script: |
| 40 | + |
| 41 | + bash $PYLITH_DIR/doc/developer/update_1.9to2.0.sh |
| 42 | + |
| 43 | + will update all .cfg files in the current directory and all |
| 44 | + subdirectories with the new names (you will need to replace |
| 45 | + $PYLITH_DIR with the directory containing the PyLith source code). |
| 46 | + |
| 47 | + |
| 48 | +PyLith allows use of the Chaco and ParMetis/Metis partitioners. The |
| 49 | +name of the ParMetis/Metis partitioner was changed from "parmetis" to |
| 50 | +"metis". |
| 51 | + |
| 52 | + [pylithapp.mesh_generator] |
| 53 | + distributor.partitioner = metis |
| 54 | + |
| 55 | +Buried edges of faults are handled differently in v2.0. A separate |
| 56 | +nodeset/pset should be created and contain the vertices on the buried |
| 57 | +edges of the fault. See the Section 6.4.2 of the PyLith manual for |
| 58 | +more information. |

| 61 | +RELEASE NOTES |
| 62 | +====================================================================== |

| 64 | +---------------------------------------------------------------------- |
| 65 | +Version 2.0.3 |
| 66 | +---------------------------------------------------------------------- |
| 67 | + |
| 68 | +* Bug fixes |
| 69 | + |
| 70 | + - Updated autotools files (Makefile.am, configure.ac) for |
| 71 | + compatibility with recent versions of automake (up to and including |
| 72 | + v1.14.1). |
| 73 | + |
| 74 | +---------------------------------------------------------------------- |
| 75 | +Version 2.0.2 |
| 76 | +---------------------------------------------------------------------- |
| 77 | + |
| 78 | +* Bug fixes |
| 79 | + |
| 80 | + - Fixed linking issue in Darwin binary distribution, primarily |
| 81 | + affecting systems with OS X 10.7 and 10.8. |
| 82 | + |
| 83 | + - Improved example journal files for CUBIT/Trelis to improve |
| 84 | + compability (examples/meshing/surface_nurbs/dem). |
| 85 | + |
| 86 | + - Updated more journal in examples so that APREPRO lines have a |
| 87 | + leading '$' instead of a '#' to differentiate from comments. |
| 88 | + |
| 89 | + - Added examples/debugging files from Crustal Deformation Modeling |
| 90 | + workshop debugging tutorial. |
| 91 | + |
| 92 | +---------------------------------------------------------------------- |
| 93 | +Version 2.0.1 |
| 94 | +---------------------------------------------------------------------- |
| 95 | + |
| 96 | +* Added example (examples/2d/gravity) for viscoelastic deformation in |
| 97 | + 2-D with gravitational body forces and small strain formulation. |
| 98 | + |
| 99 | +* Bug fixes |
| 100 | + |
| 101 | + - Improved example journal files for CUBIT/Trelis to improve |
| 102 | + compability. All journal files should work with CUBIT 14.1 and |
| 103 | + Trelis 15.0. |
| 104 | + |
| 105 | + - Created examples of IDless journal files in examples/2d/greensfns. |
| 106 | + These files should work with all recent versions of CUBIT and |
| 107 | + Trelis. |
| 108 | + |
| 109 | + - Switched journal APREPRO lines to have leading '$' instead of '#' |
| 110 | + to differentiate from comments. |
