Code Review
This pull request successfully exposes the Rayleigh-Plesset, CavitationRegimeClassifier, and HemolysisModel from the cfd-core Rust library to Python, addressing previous TODO comments and enabling proper cross-validation. The changes are well-structured and integrate new modules effectively. My review focuses on enhancing the accuracy and clarity of the validation script.
| if err > 1.0: # The py implementation uses beta for time and alpha for stress (different letters, same values roughly, need to allow slight differences or exactly match constants. Actually let's use the exact constants if possible) | ||
| pass # just print |
There was a problem hiding this comment.
The if err > 1.0: pass statement effectively disables the failure condition for individual hemolysis test cases if the error exceeds 1%. This can lead to a misleading '✓ Cross-validation PASSED' message for the entire section, even if some individual comparisons have large errors. Validation tests should accurately reflect the outcome of all comparisons.

In a validation script, it's best practice to explicitly pass all parameters to constructors, even if they match the default values in the Rust binding. This ensures that the validation is against specific, known constants rather than implicit defaults, making the test more robust and easier to understand if defaults change in the future.

The comment The py implementation uses beta for time and alpha for stress (different letters, same values roughly, need to allow slight differences or exactly match constants. Actually let's use the exact constants if possible) is misleading. The giersiepen_standard() model in Rust uses constants that exactly match the Python implementation's C, alpha, and beta values. This comment suggests a potential mismatch or a need for further action that has already been addressed by using giersiepen_standard().

The summary section incorrectly references crates/cfd-core/src/physics/hemolysis/giersiepen.rs as the location for the Rust Hemolysis implementation. The correct file is crates/cfd-core/src/physics/hemolysis/models.rs.

- Around line 81-89: The script currently only prints pass/fail messages for
each model (e.g., using err_rc, err_p comparing R_c_python vs rc_rust and
P_Blake_python vs p_blake_rust) but never updates a global status, so the
process still exits 0; add an overall failure flag (e.g., overall_success =
True) or a failed_models list at module scope, set it to False / append model
identifiers whenever a numeric tolerance check fails or a required Rust binding
is missing (the blocks that print "Cross-validation FAILED", "Rust bindings for
Cavitation not exposed", and similar blocks referenced in the file), and after
all per-model validations complete check that flag and call sys.exit(1) if any
failure occurred; ensure you update all analogous checks (the other compare
blocks and binding-missing branches) so every failure flips the global state
before the final exit decision.
- Around line 85-89: Replace all print statements that use f-string syntax but
contain no interpolation with regular string literals in
validation/cross_validate_rust_python.py; specifically change occurrences like
print(f" ✓ Cross-validation PASSED") to print(" ✓ Cross-validation PASSED")
for the flagged lines and additional instances (lines referenced in the review).
Search for print(f"...") usages in the file and remove the leading f for those
that do not include any { } placeholders, keeping f-strings intact only when
they actually interpolate variables.

Make the validation result authoritative.
These blocks only print warnings/FAILED; they never update a script-wide status, so the process still exits 0 and Line 259 reads as success once cfd_python imports. Please accumulate per-model results and sys.exit(1) when any required binding is missing or a numeric check fails.
Also applies to: 140-154, 218-232, 259-259
