:orphan: .. _release_5_3_0: ========================== v5.3.0 release notes ========================== Clawpack 5.3.0 was released on May 21, 2015. See :ref:`installing`. Changes relative to Clawpack 5.2.2 (October 28, 2014) are shown below. Changes to classic ------------------ * One example added with a pointwise Riemann solver. See `classic diffs `_ Changes to clawutil ------------------- * Added `nbtools.py` module for working with Jupyter (formerly IPython) notebooks (still work in progress). * Added ability to correctly call alternative Makefiles, e.g. :: make .plots -f Makefile_kml * Added support for preprocessing variables and flags * Added support for storm surge code See `clawutil diffs `_ Changes to visclaw ------------------ * Added support for creating `kml` files that can be viewed on Google Earth (for GeoClaw applications). See :ref:`googleearth_plotting`. * Added some support for JSAnimation in notebooks and other improvements, in particular to insure that filenames do not have extraneous spaces and fail to show up in animation. * Added support for ForestClaw * Added function `gaugetools.compare_gauges` and support for gauges in 3d. * Deprecate `plot_topo_file` and `TopoPlotData` in favor of `topotools.Topography` methods. * Some refactoring and cleaning up of code, and minor bug fixes. See `visclaw diffs `_ Changes to riemann ------------------ * Added 3d Euler equations in general geometries using f-waves. * Added 2d acoustics solvers for mapped grids. * Added some pointwise Riemann solvers for several problems in 1d and 2d. * Added `riemann_tools.py` and other code to facilitate showing Riemann solutions in notebooks. Still work in progress. See `riemann diffs `_ Changes to amrclaw ------------------ * Substantial refactoring of code, much of which should be invisible to users. * Some changes are required in any application `Makefile` to update from 5.2.2 to 5.3.0. - In 2d, remove:: $(AMRLIB)/dumpgauge.f \ - In 2d, add the files:: $(AMRLIB)/stepgrid_dimSplit.f \ $(AMRLIB)/step2x.f90 \ $(AMRLIB)/step2y.f90 \ $(AMRLIB)/flux2_dimSplit.f \ - In 3d, add the MODULE:: $(AMRLIB)/gauges_module.f90 somewhere **after** `$(AMRLIB)/amr_module.f90` in the list of modules. - In 3d, add the files:: $(AMRLIB)/stepgrid_dimSplit.f \ $(AMRLIB)/step3x.f \ $(AMRLIB)/step3y.f \ $(AMRLIB)/step3z.f \ $(AMRLIB)/flux3_dimSplit.f \ Here `AMRLIB = $(CLAW)/amrclaw/src/2d` in 2d, for example * Gauge output refactored. * Gauge output option added to 3d code. For an example, see `$CLAW/amrclaw/examples/advection_3d_swirl/setrun.py` * Dimensional splitting option added to both 2d and 3d code. To use, in `setrun.py` set `clawdata.dimensional_split` to `"split"` or `1`. * New approach to handling boundary conditions to fix bug where boundary conditions varying spatially along a boundary could not be specified. Illustrated in new `examples/advection_2d_inflow`. * `alloc` changed from pointer to allocatable, `igetsp` stack-based, * Several bug fixes, particularly in 3d code. See `amrclaw diffs `_ Changes to geoclaw ------------------ * Some changes are required in any application `Makefile` to update from 5.2.2 to 5.3.0. - add the MODULEs:: $(GEOLIB)/gauges_module.f90 \ $(GEOLIB)/surge/holland_storm_module.f90 \ $(GEOLIB)/surge/stommel_storm_module.f90 \ $(GEOLIB)/surge/constant_storm_module.f90 \ $(GEOLIB)/surge/storm_module.f90 \ $(GEOLIB)/friction_module.f90 - remove the MODULE:: $(AMRLIB)/gauges_module.f90 \ - remove the file:: $(GEOLIB)/dumpgauge.f \ Here `GEOLIB = $(CLAW)/geoclaw/src/2d/shallow`. Note that `$(GEOLIB)/gauges_module.f90` must come **after** both ` $(AMRLIB)/amr_module.f90` and `$(GEOLIB)/geoclaw_module.f90` in the list of modules. * Gauge output refactored as in `amrclaw`. Note it is now necessary to use the version of `gauges_module.f90` in `geoclaw` rather than the version from `amrclaw` since the subroutine for printing the gauges is now in this module rather than in `dumpgauge.f`. In `geoclaw`, an additional column is printed for `eta = B + h`, the sea surface, in addition to the components of `q`. * Multilayer code merged in and several routines refactored or consolidated. * New support added for creating `kml` files for plotting results on Google Earth. * Topography `topo_type` 2 and 3 are now more flexible: - The header lines can have either the number or the text first, e.g. :: NCOLS 200 or :: 200 NCOLS (In either case the label is ignored, the order of lines is all that matters). Both Python and Fortran codes now support this. - The header line for the cellsize `dx` can now have a single value or two values `dx` and `dy` for different resolutions in longitude and latitude. Previously a single value was allowed and `dx == dy` assumed. * Added support for creating `kml` files that can be viewed on Google Earth (for GeoClaw applications). See :ref:`googleearth_plotting`.
