Changelog#

The format follows Keep a Changelog. Versions follow semantic versioning, the metapackage version is updated according to the largest bump of any of the dependent packages.

0.5.0 – 2025-07-11#

Added#

mammos-entity

  • A new submodule mammos-entity.io that provides two functions to write and read CSV files with additional ontology metadata. For more details refer to the new io documentation. (PR29, PR46, PR47 )

Fixed#

mammos-entity

  • Fix bug when defining unitless entities. (PR37 and PR45)

0.4.0 – 2025-06-27#

Changed#

mammos-entity

  • The Entity class is no longer a subclass of mammos_units.Quantity. As a consequence it does no longer support mathematical operations. Use the attribute .quantity (or the short-hand .q) to access the underlying quantity and to perform (mathematical) operations. (PR28)

  • The package now comes with a bundled ontology consisting of EMMO (version 1.0.0-rc3) and Magnetic Material (version 0.0.3). Internet access is no longer required. (PR33)

mammos

  • Use Fe16N2 instead of Nd2Fe14B in hard magnet workflow. (PR17)

0.3.0 – 2025-06-11#

Added#

mammos-entity

  • New predefined entity mammos_entity.J

  • New predefined entity mammos_entity.Js

mammos-mumag

  • Optional argument plotter in plot_configuration to add a vector plot of a magnetization configuration to a pyvista.Plotter provided by the caller.

Changed#

mammos-entity

  • Return a mammos_units.UnitConversionError (inherited from astropy.units) when trying initialize an entity with incompatible units.

0.2.0 – 2025-06-06#

Added#

mammos

  • Command-line script mammos-fetch-examples to download all example notebooks.

mammos-entity

  • Entity objects have ontology_label_with_iri attribute.

Changed#

mammos-entity

  • When trying to initialize an entity with a wrong unit the error message does now show the required unit defined in the ontology.

Fixed#

mammos-entity

  • Entity.to did not return a new entity in the requested units and instead used the default entity units.

  • Entity.axis_label: unit inside parentheses instead of brackets.

0.1.0 – 2025-06-05#

Added#

mammos – 0.1.0

  • Workflows for hard magnets and sensor shape optimization.

  • Ensures compatible software components are installed.

mammos-analysis – 0.1.0

  • Calculation of macroscopic properties (Mr, Hc, BHmax) from a hysteresis loop.

  • Fitting of the linear segment of a hysteresis loop.

  • Calculation of temperature-dependent micromagnetic properties from atomistic spin dynamics simulations using Kuz’min equations.

mammos-dft – 0.3.0

  • Database lookup functionality for a selection of pre-computed materials.

mammos-entity – 0.5.0

  • Provides entities: quantities with links to the MaMMoS ontology (based on EMMO) by combining mammos-units and EMMOntoPy.

  • Helper functions to simplify creation of commonly required magnetic entities.

mammos-mumag – 0.6.0

  • Finite-element hysteresis loop calculations.

  • Requires a separate installation of esys-escript.

mammos-spindynamics – 0.2.0

  • Database lookup functionality for a selection of pre-computed materials.

mammos-units – 0.3.1

  • Extension of astropy.units that allows working with quantities (units with values) containing additional units relevant for magnetism.
