anon-closure-challenge-v2/closure-challenge-v2-cfd-casesClosure Challenge v2 — CFD case files (heavy) Companion dataset to anon closure challenge v2/closure challenge v2 . This repository hosts the full OpenFOAM cases (mesh, fields, run scripts), VTK volume snapshots, and DNS native partitioned VTUs for the 14 test cases of the Closure Challenge v2 benchmark, together with the standardized training and validation sets under data/train/ and data/validation/ . The lightweight integral profile portion needed for reproducing the scoring protocol is in the companion dataset. Most reviewers and submitters do not need this heavy dataset — it is only required for re running the CFD simulations from scratch or for extended analyses. NeurIPS 2026 Evaluations & Datasets track submission. Authors anonymised for double blind review. Code repository (scoring package, evaluation protocol, per case attribution): Contents Approximately 17 GB. 14 test cases, plus 27 training and 5 validation cases. Every case carries a converged solution and the mesh it was computed on. The 14 cases at the top level are the held out test set . Training and validation cases live under train/ and validation/ and carry the same OpenFOAM structure. Extraction and plotting ut…
