Changes to classic

  • None.

See classic diffs

Changes to clawutil

  • Consistently use CLAW_PYTHON in Makefile.common, which should point to the version of Python the user wants to use for Clawpack.

  • Make some changes to ease the transition from nose (which is no longer supported) to pytest in the future.

  • Other minor changes.

See clawutil diffs

Changes to visclaw

  • The ClawPlotAxes.title string is used by default to make a title for the plot for each time frame with the time in the units used in the problem. A new capability was added so that if title includes the string d:h:m:s then the time is assumed to be in seconds and is converted to days:hours:minutes:seconds in the title. Otherwise, if the title includes h:m:s then the time is converted to hours:minutes:seconds in the title. This is particularly useful in GeoClaw.

  • Some more attributes have been added to ClawPlotFigure, ClawPlotAxes, and ClawPlotItem to facilitate making nicer looking plots without so much need to use kwargs attributes or define an afteraxes function, for example.

    The lines below are extracted from $CLAW/visclaw/src/python/visclaw/data.py. For more information about these attributes (and others), see https://www.clawpack.org/dev/setplot.html.

    • Added to ClawPlotFigure:

    • Added to ClawPlotAxes:

      self.add_attribute('time_label_kwargs', {})  # kwargs for xlabel cmd
      self.add_attribute('kwargs', {})
      self.add_attribute('grid', None) # True to add grid() command
      self.add_attribute('grid_kwargs', {}) # argument to grid() command
      self.add_attribute('title_fontsize', None)
      self.add_attribute('title_kwargs', {}) # e.g. to set color
      self.add_attribute('title_t_format', None) # format for t in title
      self.add_attribute('xticks_fontsize', None)
      self.add_attribute('xticks_kwargs', {}) # e.g. to set ticks,rotation
      self.add_attribute('yticks_fontsize', None)
      self.add_attribute('yticks_kwargs', {}) # e.g. to set ticks
      self.add_attribute('xlabel', None) # label for x-axis
      self.add_attribute('ylabel', None) # label for y-axis
      self.add_attribute('xlabel_fontsize', None)
      self.add_attribute('ylabel_fontsize', None)
      self.add_attribute('xlabel_kwargs', {})
      self.add_attribute('ylabel_kwargs', {})
      self.add_attribute('aspect', None)
      self.add_attribute('aspect_latitude', None)
      self.add_attribute('useOffset', None)
    • Added to ClawPlotItem:


See visclaw diffs

Changes to riemann

  • None.

See riemann diffs

Changes to amrclaw

  • In 2d and 3d, valout.f90 now calls bound before dumping arrays when doing binary output (since the ghost cells are also dumped in this case).

  • On restart, do not advance the frame number if output_t0 == True, so that there is not a duplicated frame at the same time.

  • Other minor fixes.

See amrclaw diffs

Changes to geoclaw

  • Fixed fgmax_finalize.90 so that if a grid number fgno is specified for the fgmax grid then it uses this in constructing the filename for output (rather than 1,2,3 based on order specified in setrun.py)

  • Facilitate reading a topo file when at topotools.Topography object is first instantiated: the __init__ function now calls read() if path is provided as an argument.

  • fgmax_tools.FGmaxGrid.read_output function now takes an argument indexing that is ‘ij’ by default for backward compatibility, but setting to ‘xy’ results in the fgmax grid having the same layout as topo grids generated by topotools.Topography, which is often useful.

  • Added geoclaw.data.FGmaxData.read() function to read in the data from a fgmax_grids.data file.

  • Added sphere_source as local variable in src/2d/shallow/src2.f90, set to 0 for now for backward compability. This allows testing the addition of source terms that should be included on the sphere but were always missing. After further testing, the plan is to change the default in the next major release v5.10.0 and also allow this to be adjusted in setrun.py. See https://www.clawpack.org/dev/sphere_source.html for more information.

  • Other minor fixes.

See geoclaw diffs

Changes to PyClaw

  • Some fixes in ASCII output for compatibility with Fortran versions.

  • Other minor fixes.
