L. Lederer and T. Vock. It includes two Python scripts (`convergence.py`, `convergence_3d.py`) that solve the Stokes equations on the unit square (resp. unit cube) with a manufactured smooth solution, using the MINI, stabilized equal-order $P^kP^k$, and Taylor--Hood finite elements, both with the standard method and with the pressure-robust method proposed in the paper (in which the right-hand side force is replaced by its Nédélec interpolant). It also includes the raw error/convergence data (`conv_data/`) generated by these scripts, from which all convergence tables in the paper's numerics section are directly computed. See README.md for software requirements, instructions to reproduce the data, and a file-to-table mapping.</p>","doi":"10.25592/uhhfdm.21546","license":{"id":"CC-BY-4.0"},"publication_date":"2026-09-16","related_identifiers":[{"identifier":"10.25592/uhhfdm.21545","relation":"isVersionOf","scheme":"doi"}],"relations":{"version":[{"count":1,"index":0,"is_last":true,"last_child":{"pid_type":"recid","pid_value":"21546"},"parent":{"pid_type":"recid","pid_value":"21545"}}]},"resource_type":{"title":"Dataset","type":"dataset"},"title":"Reproducibility package: Pressure-robustness by commuting interpolation operators for Stokes discretizations with continuous pressures"},"owners":[1008],"revision":2,"updated":"2026-09-28T11:24:29.909740+00:00"}
