FElupe: Finite element analysis for continuum mechanics of solid bodies

[9.5.0] - 2025-11-05

Added

• Add a JOSS badge to README.md and change CITATION.cff to JOSS.
• Add the keyword Job.evaluate(tqdm="tqdm") and newtonrhapson(tqdm="tqdm") with additional options "auto" and "notebook". The tqdm-keyword allows to switch the tqdm-backend manually. Note that in a Jupyter console, a progress bar from tqdm.auto does not update.
• Add the hessian() method to the ArbitraryOrderLagrange element and also for BiQuadraticQuad and TriQuadraticHexahedron.
• Add mesh.subdivide() and Mesh.subdivide() to refine a mesh with quad, hexahedron, triangle or tetra cells.

Changed

• Change the recommended citation from Zenodo to JOSS in README.md.

Fixed

• Fix the XDMF output error if a global field in Job.evaluate(x0=field) is based on RegionVertex. Fall-back to a basic output with only points and default point-data.
• Fix the magnitude in PointLoad.plot() for 2d-models in 3d-space, e.g. for truss bodies. Use the max. distance per axis instead of the min. distance per axis for the base magnitude of the force arrow(s).
• Change the mask-argument of a Boundary from a boolean array to an array-like argument, which is converted to a boolean array internally. This will handle integer mask-arrays correctly.
