[1.0.0] - 2026-xx-yy

The “Solver-Agnostic” Release

Added

  • PyVista Backend: Complete integration with pyvista for mesh handling, integral calculations and visualization.

  • Numpy-native: All algorithms now accept standard numpy arrays, removing the need for FEM objects.

  • Universal Input: Support for importing results from OpenFOAM, Ansys, and any VTK-supported solver.

  • New Tutorials: Added tutorials for non-FEniCS workflows (e.g., fluid dynamics with external data).

Changed

  • Removed Dependency: Dropped dolfinx and mpi4py as core dependencies.

  • Refactor: POD, EIM, SGreedy and other classes now operate on matrix inputs rather than FEM functions.

  • Docs: Completely rewritten documentation to reflect the new architecture.

  • Improved installation speed and compatibility with Linux/macOS.

[0.1.3] - JOSS paper published 2026-01-09

The “JOSS Submission” Release

Added

  • Implementation of POD, EIM, GEIM, and PBDW algorithms based on dolfinx.

  • Support for distributed computing via MPI.

  • Original application cases for Nuclear Engineering (Circulating Fuel Reactor).

Reference

  • The original version corresponds to the implementation described in the JOSS paper: Riva et al., “pyforce: Python Framework for data-driven model Order Reduction of multi-physiCs problems”
