FloPy 3.8.1

Version 3.8.1

This release includes various bugfixes as well as model splitter improvements. It also adds some capabilities for the soon forthcoming MF6 surface water model. Since the latter is still under development and not yet officially available, we do not consider these to be full-fledged features yet, and so this is a patch rather than a minor FloPy release.

New features

  • feat(cell1d): Add support for 1D vertex grids (#2296). Committed by langevin-usgs on 2024-08-23.

FloPy 3.5.0

Version 3.5.0

⚠️ Breaking changes

  • rno, iuzno, lakeno, wellno attributes were standardized to ifno (for "feature number") — a 3.5.x patch may provide backwards-compatibility as this was released somewhat prematurely

Highlights

Python 3.12 support

While previous releases may be compatible with Python 3.12, this release adds official support. Note: the wheel for pyzmq, a core dependency of IPython/jupyter, may fail to build when installing optional dependencies via e.g. pip install "flopy[test]" or pip install "flopy[optional]". To work with notebooks in the meantime Conda is recommended.

Pandas integration
  • Promote Pandas from optional to core dependency (note pandas >= 2 is required)
  • Reimplement MF6 internal data storage with Pandas — may provide significant speedups reading/writing MF6 input files. To fall back to the old implementation, set use_pandas=False on MFSimulation.load() or at init time.
  • Support DataFrame for flopy.modflow.* package input data, e.g. node_data and stress_period_data
Deprecations

Several deprecated features are removed or turned into errors:

  • sr property from Mt3dms
  • flopy.export.vtk functions export_model(), export_package(), export_transient(), export_heads(), export_array(), export_cbc()
  • flopy.plot.plotutil functions centered_specific_discharge(), cvfd_to_patch_collection(), plot_cvfd()
  • layer kwarg in MFTransientArray's get_data() method
  • MFSimulation functions get_mvr_file(), get_mvt_file(), get_gnc_file(), get_ims_package()
  • nwt_11_fmt parameter from ModflowUzf1 initializer
  • Grid.thick and .saturated_thick properties
Other changes
  • rno, iuzno, lakeno, wellno standardized to ifno (for "feature number")

Several features are newly deprecated:

  • ra_slice() from flopy.utils.recarray_utils, suggest numpy.lib.recfunctions.repack_fields()
  • recarray() from flopy.utils.recarray_utils, suggest numpy.core.records.fromrecords()
  • epsg, proj4, and proj4_str are replaced with a single crs parameter on MF6 Grid and ModflowDis classes and various utilities
  • branch option for flopy.mf6.utils.generate_classes utility replaced with ref

See specific commits below for more info on suggested replacements.

FloPy 3.4.3

Version 3.4.3

Provide interim support for Matplotlib 3.8+, which changed the way contours are represented and broke export_contours() and export_contourf().

Note: with MPL 3.8+, FloPy can no longer export interior polygons (i.e. holes) for filled contours. This is a backwards-incompatible change, and could be considered worthy of a major release — with some compunction, FloPy follows MPL's example here, and this remains a patch release. A future version may reimplement contour export and restore support for interior polygons. In the meantime, users requiring interior polygons should pin MPL below 3.8.
