v5.6.0 release notes

Clawpack 5.6.0 was released on June 2, 2019. See Installing Clawpack.

Changes relative to Clawpack 5.5.0 (Aug 28, 2018) are shown below.

To see more recent changes that are in the the master branch but not yet released, see Changes to master since v5.6.0.

Changes that are not backward compatible

  • A new approach to flagging cells for AMR refinement was added in 1d and 2d amrclaw and in geoclaw (see notes below). This led to the addition of a new adjoint.data file created by running setrun.py. If adjoint error flagging is not being used then this file is still expected by the Fortran code.
  • Many Fortran routines changes for adjoint flagging and some new modules were added, resulting in changes to the Makefiles used in amrclaw and geoclaw (see below).

General changes

  • None so far.

Changes to classic

Nothing major.

See classic diffs

Changes to clawutil

  • A new attribute data.ClawRunData.adjointdata was added, which points to an object of class amrclaw.data.AdjointData containing information about inputs needed for adjoint flagging.

See clawutil diffs

Changes to visclaw

  • Numerous minor improvements.

See visclaw diffs

Changes to riemann

  • HLLE solvers added for the Euler equations and 1d and 2d shallow water.
  • Riemann solvers added for the adjoint of the linearized shallow water equations in non-conservative form, as needed for adjoint flagging.
  • Note that other adjoint Riemann solvers for amrclaw examples had already been added in v5.5.0.

See riemann diffs

Changes to amrclaw

  • A new approach to flagging cells for AMR refinement was added in 1d and 2d (not yet in 3d), based on first solving an adjoint equation and then taking inner products of the forward solution at each regridding time with snapshots of the adjoint solution. This is described in http://www.clawpack.org/dev/adjoint.html and http://www.clawpack.org/dev/refinement.html. This was developed over the past several years, primarily by @BrisaDavis, and required refactoring several routines. Some of these changes were already included in version 5.5.0.
  • In amrclaw/src/1d, new the Fortran module adjoint_module.f90 was to support adjoint flagging, and Makefile.amr_1d updated.
  • In amrclaw/src/2d, new Fortran modules adjoint_module.f90 and adjointsup_module.f90 were added to support adjoint flagging, and Makefile.amr_2d updated.
  • class amrclaw.data.AdjointData added, to contain information about adjoint error flagging.
  • moment.f was refactored as moment.f90.

See amrclaw diffs

Changes to geoclaw

  • The adjoint flagging option was also added to GeoClaw, resulting in many changes to geoclaw routines.
  • In geoclaw/src/2d/shallow, new Fortran modules adjoint_module.f90 and adjointsup_module.f90 were added to support adjoint flagging, and Makefile.geoclaw updated.
  • These modules were also added to src/2d/shallow/multilayer/Makefile.multilayer, although adjoint flagging has not been implemented yet for the multilayer equations.
  • New capabilities were added to src/python/geoclaw/surge/storm.py for reading storm tracks.
  • topotools.read_netcdf was improved to more robustly handle coarsen == 1
  • The url was fixed in examples/tsunami/chile2010/maketopo.py that caused a webpage to be downloaded instead of the topofile needed for this example, caused by incorrect url resolution of geoclaw.org.
  • A typo was fixed in dtopotools.SubFault.dynamic_slip that caused failure.
  • Numerous other minor fixes and improvements.
