ASPECT
Changes after the latest release (v1.5.0)

This is the list of changes made after the release of Aspect version 1.5.0. All entries are signed with the names of the author.

  1. Changed: With a sufficiently new deal.II (9.0.0.pre), the spherical shell geometry no longer uses boundary objects, but lets the SphericalManifold class handle all geometry tasks. Using older version of deal.II the manifold is used for mesh refinement, and boundary objects are used otherwise. This results in improved meshes for the side boundaries of octants of 3D spheres in both cases.
    (Anne Glerum, Rene Gassmoeller, 2017/04/19)

  2. Changed: Entries about new contributions are not longer stored in doc/modules/changes.h, but instead each contribution is stored as a single file of the form YYYYMMDD_name in doc/modules/changes/. This creates less conflicts when multiple parallel branches are merged.
    (Rene Gassmoeller, 2017/04/17)

  3. Changed: The visco_plastic material model now uses a single compositional field for strain weakening, which can be calculated with the integrated strain invariant particle property or an equivalent compositional field plugin located in the benchmark buiter_et_al_2008_jgr.
    (John Naliboff, 2017/04/14)

  4. Changed: The folder benchmark/ was renamed into benchmarks/ to be consistent with our directory tests/.
    (Rene Gassmoeller, 2017/04/14)

  5. Changed: aspect now outputs only relative nonlinear residuals of nonlinear iterations in the screen output. In addition, the number of the nonlinear iteration is included in the screen output.
    (Juliane Dannberg, 2017/04/13)

  6. New: Aspect now supports postprocessing of nonlinear iterations, in particular generating graphical output for each iteration.
    (Juliane Dannberg, 2017/04/12)

  7. New: aspect now provides as script that – when used together with the deal.II parameter GUI program – allows for a graphical creation and modification of input parameter files. All available parameters are listed, including their documentation, type, allowed range, and default value. The parameter file written by the GUI will only contain values that are different from the default values, to keep the file easily readable.
    (Timo Heister, Rene Gassmoeller, Juliane Dannberg, 2017/03/28)

  8. New: aspect now supports the –output-xml flag to generate .xml parameter files that can be edited using the deal.II parameter GUI.
    (Timo Heister, 2017/03/24)

  9. New: Compressible computations now work with discontinuous pressure elements.
    (Timo Heister, 2017/03/23)

  10. New: The box geometry can now include initial topography.
