I am pleased to announce the release of PyLith 2.2.2, a finite-element
code designed to solve dynamic elastic problems and quasi-static
viscoelastic problems in tectonic deformation.

This release provides a small number of bugfixes.

You can download the source code and binaries from the PyLith web page

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.

  • Bug fixes

    • Fix several typos in the manual.

    • Fix order of deallocation of data members in ElasticMaterial to prevent a segmentation fault, thereby allowing error messages to be shown when throwing an exception.

    • Fix tests for MPI and PETSc version info for more use cases.

    • Ensure all Python script are executable and use nemesis is used instead of python for correct paths to modules on Darwin.

  • Added ability to write residual to an HDF5 file during solves. This is intended for debugging and is enabled at runtime using --journal.debug.formulation=1. The residual will be written to residual.h5. To generate the associated .xdmf file run pylith_genxdmd -f residual.h5.

  • Updated to PETSc 3.10.2
