* feat(cubics): add Chebyshev superancillaries for SRK and Peng-Robinson EOS (#2739)
Port piecewise Chebyshev superancillary expansions from teqp for SRK and PR
cubic EOS, providing fast and accurate saturation properties without iterative
flash. Adds `calc_saturation_ancillary`, `update_QT_pure_superanc`, and
`calc_superanc_Tmax` on `AbstractCubicBackend`; vdW data omitted as CoolProp
does not expose a vdW backend.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* refactor(cubics): address review feedback on cubic superancillary
- Fix stale comment on calc_superanc_Tmax (no Newton steps; closed-form)
- Move SRK_CODE/PR_CODE/P_CODE/RHOL_CODE/RHOV_CODE constants before
supercubic() so switch cases use named constants instead of magic ints
- Add T > Tmax guard in calc_saturation_ancillary and update_QT_pure_superanc
to throw CoolProp ValueError instead of propagating std::invalid_argument
- Add is_pure_or_pseudopure guard in calc_superanc_Tmax
- Near-Tc test now derives pc from the superancillary itself rather than
AS->p_critical() (which reflects the real fluid, not the cubic model)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* docs(cubics): document SRK/PR superancillary APIs with timing and citation
Add a Superancillaries for SRK and PR subsection to the Cubic EoS docs
covering update_QT_pure_superanc and saturation_ancillary, their
constraints (pure-only, PR/SRK-only, T-input, T <= Tc, not used by
PropsSI), a %timeit comparison against the full cubic flash, and a
citation to Bell and Deiters, IECR 2021 (added to the bib library).

* Add refrigerant mixture models (Bell-JPCRD-2022/2023) and update R-1234yf EOS
Pure fluid:
- Replace Richter-JCED-2011 with Lemmon-Akasaka 2022 (Int. J. Thermophys. 43:119)
as EOS[0] for R-1234yf; retain Richter as EOS[1]

BibTeX entries added: Bell-JPCRD-2022, Bell-JPCRD-2023, Lemmon-IJT-2022
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Add C++ check value tests for Lemmon-IJT-2022 and Bell-JPCRD-2022/2023
- Table 7 from Lemmon & Akasaka (2022): 6 state points for R1234yf
covering ideal-gas, gas, compressed liquid, and near-critical
- Fixed-point constants: Tc, pc, rhoc, Ttriple
- Table XI from Bell (2022): alphar check values for three R1234yf-based
binary pairs (R1234yf/R1234zeE, R1234yf/R134a, R134a/R1234zeE)
- Table XIII from Bell (2023): alphar check values for five mixture pairs
(R32/R1234yf, R32/R1234zeE, R125/R1234yf, R1234yf/R152a, R1234zeE/R227ea)

* feat: add superancillary equations to R1234yf EOS
Builds Chebyshev superancillary for R1234yf covering the full

intervals). Also adds missing 'description' fields to the ANCILLARIES
block (required by the teqp ancillary loader).

* fix(mixtures): correct betaT ordering for R1234zeE pairs; add inverted-order tests
The Bell-JPCRD-2022 JSON entries for R1234yf+R1234zeE and R134a+R1234zeE
had CAS1=R1234zeE (alphabetically first), causing no swap on load. When
the mixture was constructed with the other component first CoolProp's
MixtureParameters swap logic inverted betaT a second time, yielding the
wrong reducing temperature.
Fix: swap CAS1/CAS2 so that CAS1 is alphabetically later for both pairs,
triggering a swap-on-load that pre-inverts betaT at full double precision.
The swap-on-use then recovers the exact paper value with no rounding error.
The original paper betaT/betaV values are restored in the JSON.
Also enable DmolarT_INPUTS on mixture backends in DHSU_T_flash so the
alphar check-value tests can call update(DmolarT_INPUTS, ...) on a mixture
AbstractState without throwing.
Test updates:
- Bell-JPCRD-2022 Table XI check values for R1234yf-containing pairs
updated to the final Lemmon-IJT-2022 EOS (pre-pub EOS used in paper
differs by ~0.4%); tolerance tightened from 1e-6 to 1e-10 throughout.
- Three new inverted-component-order sections check the same tabulated
alphar values as the forward-order tests, verifying that the GERG
reducing function symmetry (swap components + reciprocal beta = same
result) is preserved by the CAS-ordering fix.

* fix(tests): specify phase in mixture DmolarT tests; revert FlashRoutines workaround
Mixture tests that call update(DmolarT_INPUTS, ...) must call specify_phase()
first so DHSU_T_flash uses the imposed-phase path rather than hitting the
NotImplementedError. Reverts the iDmolar special-case added to the mixture
else-branch of DHSU_T_flash.

* build: replace git submodules with CPM.cmake
All 11 submodules (Eigen, fmtlib, msgpack-c, rapidjson, IF97,
REFPROP-headers, multicomplex, Catch2, pybind11, ExcelAddinInstaller,
FindMathematica) are now fetched by CPM.cmake at configure time.
Set CPM_SOURCE_CACHE (e.g. ~/.cache/CPM) to share the download cache
across git worktrees and build directories — no more per-worktree
`git submodule update --init --recursive`.
Vendored deps that have no upstream release cycle (miniz, nlohmann-json,
incbin) remain in externals/ as before.
Source-level changes: angle-bracket includes for rapidjson, IF97, and
REFPROP-headers now that their directories are on the include path via
CPM-provided source dirs rather than relative paths from the repo root.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(python): wire up CPM.cmake in Python wrapper, fix include paths
The Python wrapper CMakeLists.txt was still referencing submodule paths
(externals/Eigen, externals/fmtlib, externals/msgpack-c) removed by the
CPM migration. Include CPM.cmake + dependencies.cmake from the root and
use the ${Pkg_SOURCE_DIR} variables instead. Also adds missing
rapidjson, IF97, and REFPROP_headers include dirs required by CoolProp
sources.
CI workflows drop the now-meaningless `submodules: recursive` checkout
option and add a CPM source-cache step to avoid re-downloading on each
macOS/Windows runner.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* docs: remove git submodule references after CPM.cmake migration
Dependencies are now managed by CPM.cmake (fetched automatically at
CMake configure time), so git submodules no longer exist.
- Drop `--recursive` from all `git clone` commands in Web docs and
wrapper READMEs (26 .rst/.md files)
- Remove `submodules: recursive` from all CI workflow checkout steps
(13 workflow files)
- Remove `git submodule foreach/update` calls from release.bsh and
delete the now-dead pybind11 security-workaround lines
- Drop `--recursive` from build_swigged_matlab.sh and gitMirror.bsh
- Update CONTRIBUTING.md: drop "and its submodules" phrasing
Changelog entries referencing old submodule PRs are left intact as
historical records. The --recursive in buildbot.rst is for the
Dockerfiles repo (unrelated) and is also left unchanged.

* fix(ci): remove empty 'with:' blocks after submodule removal, apply clang-format
After removing 'submodules: recursive' from checkout steps, some workflow

rejects as workflow file errors. Remove the empty 'with:' in 9 workflows.
Also apply clang-format to fix spacing in REFPROPMixtureBackend.cpp,
HumidAirProp.cpp, and Helmholtz.cpp.

* feat: add Chlorine (Cl2) fundamental equation of state
Implements the EOS from Thol, Herrig, Span, Lemmon (AIChE J. 67, e17326,
2021, DOI: 10.1002/aic.17326) for chlorine (CAS 7782-50-5).
- 10-term polynomial/exponential residual + 5-term Gaussian bell-shaped
- Ideal gas: diatomic (2.5) + 3 Planck-Einstein terms (800/3000/8200 K)
- NBP reference state (h=0, s=0 at saturated liquid, 101325 Pa)
- Saturation ancillaries: pS, rhoL, rhoV from REFPROP coefficients
- Valid range: 172.17 K to 525 K, up to 20 MPa
- Adds BibTeX entry Thol-AICHE-2021
Closes#2714

* feat: add superancillary equations to Chlorine EOS
Builds Chebyshev superancillary for Cl2 covering the full saturation
curve from Ttriple (172.17 K) to near-critical (416.865 K, 61
intervals). Errors away from the critical region are at machine-
precision level (~1e-13 %).
The fastchebpure builder was also patched to prune near-critical
intervals where the pressure Chebyshev expansion becomes non-monotone
due to ill-conditioned VLE convergence at very small Theta; 3 such
intervals were removed for Chlorine (Theta ~ 2.3e-7).

* docs: add predefined mixtures table to Mixtures documentation
Adds a new section "Predefined mixtures" to Web/fluid_properties/Mixtures.rst

Each mixture is tested at build time; those that fail (missing binary interaction
parameters or not present in the compiled library) are flagged in a Notes column.
Also updates the code examples in the new section to use the required .mix suffix,
and registers the generation script in the doc build task list.

* docs: improve predefined mixtures table error messages and auto-count
- Replace CAS numbers with fluid names in binary interaction parameter errors
- Detect and report missing pure fluids by name
- Distinguish 'not registered as predefined mixture' from missing BIP

* feat(docs): add interactive 3D molecule viewers to fluid pages
Use py3Dmol + PubChem SDF data to embed a rotate-and-drag 3D (or 2D
fallback) molecule viewer on each pure fluid documentation page.
- fetch_pubchem_sdf(): downloads 3D conformer SDF from PubChem REST API
(falls back to 2D), caching results in molecule_sdf/ to avoid repeated
network calls on doc rebuilds
- generate_3dmol_rst(): inlines the SDF as a JS template literal inside a
.. raw:: html block — no extra static files needed at Sphinx build time
- FluidGenerator.write(): validates InChIKey with regex before fetching;
pseudo-pure fluids (Air, R404A, etc.) without InChIKeys are silently skipped
- conf.py: loads 3Dmol.js from CDN via html_js_files
- .gitignore: excludes the generated molecule_sdf/ cache directory
Restores molecule visualisation that was removed in April 2025 (the old
approach tried to embed an image directive inside a CSV table, which is
invalid RST; this implementation places the viewer in the RST template).

* fix(docs): serve 3Dmol.js locally to eliminate CORS errors
Download 3Dmol-min.js to _static/ at Sphinx build time (same pattern
as MathJax) instead of loading it from the CDN via html_js_files.
Serving the script same-origin removes the cross-origin restriction
that caused CORS errors when docs were opened from file:// or a local
dev server.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(docs): correct 3Dmol viewer positioning and initialization timing
3Dmol.js sets its canvas to position:absolute;top:0;left:0 and only
auto-sets the container to position:relative when the container's
inline style.position === "static". An unstyled div has style.position
=== "" so the check fails, and the canvas escapes the container and
anchors to the nearest positioned ancestor in the Sphinx page layout.
Fix: add position:relative explicitly to the viewer container div.
Also defer viewer init via DOMContentLoaded so layout is finalized
before createViewer reads the container dimensions, and call v.resize()
before v.render() to sync the WebGL canvas to the container size.

* fix(docs): disable MathJax SRE to prevent CORS errors on file:// URLs
MathJax 4.0's Speech Rule Engine fetches sre/mathmaps/base.json at
runtime via fetch(). Chrome blocks this when docs are opened from a
local file:// URL (null origin). Disabling enableExplorer and
enableAssistiveMml prevents SRE from initialising entirely.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(docs): load 3Dmol before require.js to fix AMD conflict
sphinx.ext.mathjax injects require.js at priority 500. When 3Dmol
loads after it, AMD detection fires and calls define([], factory)
instead of setting window.$3Dmol directly. Since nothing ever calls
require(['3Dmol-min']), the factory never runs and the viewer silently
fails (infinite setTimeout retry, no console errors).
Setting priority 450 ensures 3Dmol loads before require.js.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(docs): add retry logic to downloads in conf.py using requests
Replace urllib.request.urlretrieve with a requests-based _download()
helper that retries up to 5 times (exponential backoff, factor=2) on
transient HTTP errors and timeouts. Fixes CI build failures when
the MathJax or 3Dmol.js downloads time out.
