Unreleased

TBD

2.0.1 - 2024-11-20

Allow use of pymech with NumPy 2.x

Changed

  • Removed upper bound for Numpy from packaging metadata, pyproject.toml

2.0.0 - 2024-10-09

Supports Python 3.9 and above, from now on to make use of concise type-annotations. Constraints support for Numpy versions < 2.0.

Added

  • New function {func}pymech.meshtools.gen_box to generate box meshes
  • New function {func}pymech.meshtools.map2D to apply 2D coordinate transformations to meshes
  • {mod}pymech.meshtools examples in the documentation

Changed

  • Support for multiple fields with different boundary conditions in several {mod}pymech.meshtools functions
  • Explicitly raises ValueError instead of logging with critical or error levels.

Removed

Previously deprecated features are now removed

  • Module {ref}exadata is removed in favour of {mod}pymech.core. See {ref}exadata for more information on migrating your code.
  • Function {func}pymech.vtksuite.exa2vtk is removed in favour of {func}pymech.vtksuite.hexa2vtk.

1.5.0 - 2022-11-25

Added

  • Citeable in Zenodo!
  • New extra dependency groups for install as pip install pymech[opt] and pip install pymech[vtk] respectively. There is also a [full] group which implies both [opt] and [vtk].
  • {doc}asv_bench/README in documentation.
  • Dataclass {class}pymech.neksuite.field.Header using attrs for reading file headers
  • Function {func}pymech.neksuite.field.read_header
  • Module {mod}pymech.meshtools for manipulating meshes
  • Xarray backend pymech. See {ref}dataset
  • Function {func}pymech.neksuite.readma2

Changed

  • Attributes lr1 and var {class}pymech.core.Elem are tuples instead of lists
  • Attributes of {class}pymech.core.DataLims are now immutable tuples
  • {func}pymech.dataset.open_mfdataset is now a partial function. This change should be fully backwards compatible
  • {func}pymech.neksuite.readnek has a dtype option to set the floating point data type.
  • {mod}pymech.neksuite is now a sub-package with three modules.

Deprecated

  • Module {ref}exadata is deprecated in favour of {mod}pymech.core. See {ref}exadata for more information on migrating your code.
  • Function {func}pymech.vtksuite.exa2vtk is deprecated in favour of {func}pymech.vtksuite.hexa2vtk.

Removed

Fixed

  • Logging configuration which does not break other loggers.

1.4.1 - 2021-05-07

Backwards compatible release with a lot of housekeeping and some usability improvements. This will be the last release to support Python 3.6 and Xarray < 0.18.0

Added

  • Common function available from the top-level import pymech as pm
  • Extras requirements to install mayavi and rich with pip install 'pymech[full]'
  • Experimental {func}pymech.vtksuite.writevtk
  • Environment variable PYMECH_DEBUG to control logging level. See {mod}pymech.log

Changed

  • Swap optional colorlog logger with rich in {mod}pymech.log
  • Refresh {func}pymech.vtksuite.exa2vtk implementation on an experimental basis

Fixed

  • Format entire code base with black
  • Improve docs

1.4.0 - 2020-11-16

Added

  • Functions readre2 and writere2 to read/write binary .re2 Nek5000 meshes

Fixed

  • indexing bug in the boundary conditions parameters in readrea

Changed

  • Ignore some invalid 'E' internal boundary conditions in readrea since they are written this way by re2torea and ignored by Nek5000.

1.3.3 - 2020-09-29

Fixed

  • Various fixes -- including writing element map, correct order for min/max metadata -- in writenek

Added

  • {meth}pymech.core.HexaData.merge to merge meshes together and build proper connectivity

1.3.2 - 2020-09-23

Fixed

  • writenek detects system endianness and byte-swaps arrays, if needed, before writing

Removed

  • Warnings while reading/writing scalars

1.3.1 - 2020-09-17

Changed

  • use ndarray.tofile() for faster output

1.3.0.post0 - 2020-07-16

Fixed

  • Packaging issue of sdist and wheel. Now uses find_packages instead of package name.

1.3.0 - 2020-07-16

Added

  • Dataset module which extends xarray

Changed

  • Faster readnek function uses less for loops
  • Lazy load {class}pymech.core.DataLims limits as properties
  • Autogenerate documentation using sphinx extension autodoc

1.2.0 - 2020-03-18

Added

  • License GPL v3 or later

Changed

  • Miscellaneous improvements in documentation, testing and packaging
