Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.5.0] - 2026-08-03

Add code_aster as a second supported solver: generate, run, and monitor finite-element campaigns alongside Code_Saturne.

Added

  • code_aster solver adapter (solver = "code_aster"): finds the case's .export setup file, launches run_aster in docker or apptainer/singularity containers (native runtime not implemented yet), routes the solver message file to RESU/LOGS/run_solver.log, and derives case status from code_aster's DIAGNOSTIC JOB line (OK/alarm → DONE; abort, error, no-convergence, CPU/memory limits → FAILED), ignoring logs left over from previous runs when a case is relaunched
  • code_aster dashboard branding: the header shows the code_aster logo for code_aster campaigns, and favicon-code_aster.svg ships in frontend/static/ for the solver-aware favicon introduced in 0.4.1
  • examples/codeaster-cube: a complete 9-case demo campaign (cube under triaxial traction, two mesh variants, one deliberately failing case) with template .comm/.export files and the Salome script that produced the meshes

[0.4.1] - 2026-07-17

Deepen the solver adapter boundary (dashboard panels, timing columns, compare kinds, and error files are now adapter-driven), make mesh_mode = "symlink" the default with full container-runtime support, and validate DOE specs against the template.

Changed

  • Dashboard branding is solver-aware: the header shows the Code_Saturne logo only for code_saturne campaigns (other solvers get their name as text), and the favicon defaults to the Simvia mark, switching to /favicon-<solver>.svg when such an asset exists (favicon-code_saturne.svg ships today; a future solver just drops a file in frontend/static/)
  • The compare panel's file list and the Recent Errors file selector are now driven by the solver adapter via /api/app_config (compare_kinds with honest labels — first entry is the default, from which default_compare_kind now derives — and error_files from anomaly_file_names), with the previous hardcoded lists kept as fallbacks for older backends
  • The Timing Snapshot panel is now driven by the solver adapter end to end: adapters declare performance_columns (key, label, kind) which /api/perf exposes and the frontend renders (table and CSV export), and performance_fields (CLI CSV export) derives from the same metadata so the column order matches the UI; dashboard cards are declared per adapter (dashboard_panels, exposed via /api/app_config), so a future solver without residuals simply doesn't show that card — adding a solver requires no frontend or core changes
  • mesh_mode = "symlink" now works with the docker and singularity runtimes: symlinked MESH/POST targets are bind-mounted into the container at their absolute host path (MESH read-only, POST writable), for direct runs and Slurm scripts alike, so the symlinks in RUNS/ resolve identically inside the container; the up-front rejection now only fires for broken symlink targets
  • mesh_mode defaults to symlink (was copy): physically duplicating multi-gigabyte meshes per study is now opt-in; the Windows fallback to copy-with-warning when symlinks cannot be created is unchanged

Fixed

  • The Log Tail panel now offers every file its priority table declares (csauto.stdout, csauto.stderr, listing, run_status.running) instead of only *.log/summary names, so solvers whose console log is csauto.stdout (e.g. su2) get a working tail instead of "No log data available"
  • Recent-errors scanning deduplicates resolved file paths, so adapters aliasing several conventional names onto one file can no longer report the same error twice

Added

  • csauto doe cross-checks spec parameter names against the template's placeholders and IF-condition variables (./TEMPLATE by default, --template DIR to override, --no-check to skip): a spec parameter matching nothing in the template is an error — previously a typo silently produced cases that ran with the template's hardcoded value — and template variables not covered by the spec produce a warning
  • csauto prepare --strict turns the "DOE columns not used in template" warning into an error

[0.4.0] - 2026-07-15

Introduce a solver adapter boundary: all code_saturne-specific logic (command building, output parsing, file conventions, restart, live control, doctor checks) now lives behind a pluggable SolverAdapter selected via the new solver key in csauto.toml, so additional solvers can be added without touching the core.

Added

  • solver configuration key in csauto.toml selecting the solver adapter (default code_saturne)
  • SolverAdapter boundary (csauto/solvers/): the protocol, the code_saturne adapter, and an adapter registry; adding a solver means writing one adapter class, with no changes to the orchestration core (enforced by a source-scan test)
  • Built-in stub solver adapter, used by integration tests to exercise the full prepare → run → status → control pipeline without a real solver installed
  • Documentation: "Adding a new solver" step-by-step guide (docs/adding-a-solver.md) and a "Solver adapter boundary" section in docs/architecture.md

[0.3.1] - 2026-07-09

Add a mesh_mode option so large shared MESH/POST directories can be symlinked into RUNS/ instead of physically copied, with a guard against unsupported symlink + container-runtime combinations.

Added

  • mesh_mode config/CLI option (copy|symlink, default copy) for csauto prepare: symlink links the shared MESH/POST dirs into RUNS/ instead of copying them, avoiding disk duplication for large meshes; csauto run rejects docker/singularity runtimes when a symlinked mesh points outside RUNS/, since those runtimes only bind-mount RUNS/

[0.3.0] - 2026-07-08

Add csauto control for live case steering (stop/extend/checkpoint/flush) as a non-destructive alternative to killing a running case.

Added

  • csauto control command for live case steering: --stop (graceful stop with checkpoint), --extend N (raise the time step limit by N without restarting), --checkpoint (checkpoint now, keep running), --flush (flush logs/time plots now), plus a matching POST /api/control_case endpoint
  • Status panel gains a Stop button and a More menu (Extend, Checkpoint, Flush) for running cases, with toast notifications on success

[0.2.0] - 2026-07-07

Add a csauto doe command to generate doe.csv from a parameter spec, plus release automation improvements.

Added

  • csauto doe command to generate doe.csv from a TOML parameter spec, supporting factorial, Latin Hypercube (LHS), Sobol (requires the doe extra), and central composite (CCD) sampling
  • Automatic GitHub release creation when VERSION changes on main

Fixed

  • Tests no longer send real telemetry pings
  • Release workflow now gates on CI success

[0.1.1] - 2026-07-06

Fix DOE CSV parsing to tolerate whitespace around headers and values.

Added

Fixed

  • DOE CSV files with spaces around delimiters (e.g. after a comma) or leading/trailing whitespace on headers and values are now parsed correctly; whitespace is stripped before column matching and value casting, while spaces inside quoted values are preserved.

[0.1.0] - 2026-04-10

Added

  • Case generation from DOE CSV + template directory (prepare)
  • Local and Slurm job execution (run)
  • Terminal status overview (status)
  • Web monitoring dashboard (serve) with FastAPI
  • Residual, probe, and profile SVG plotting
  • Live log tailing and anomaly detection
  • Restart from checkpoint with iteration/time targets
  • Side-by-side input file comparison
  • Cleanup of old RESU directories (cleanup)
  • Environment validation (doctor)
  • Support for native, Docker, and Singularity runtimes
