-## Technical Challenges to Address - -### 1. Coordinate System Mismatch -- VMEC uses straight field line coordinates -- GVEC uses theta* (geometric poloidal angle) -- Need transformation layer or unified coordinate system - -### 2. Flux Surface Averaging -- Currently relies on VMEC's internal representations -- Need field-agnostic algorithm for surface integrals -- May require additional methods in MagneticField interface - -### 3. Performance Considerations -- Direct VMEC calls are highly optimized -- Abstract interface adds overhead -- Need careful optimization to maintain performance - -### 4.

golden record system to support multi-file comparisons MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add compare_files_multi.py for comparing multiple output files - Update compare_golden_results.sh to handle classifier_fast test case - Support comparison of additional output files: * avg_inverse_t_lost.dat, class_parts.dat, confined_fraction.dat * fort.* files (10000, 10022, 20000, 40022, 40032, 50022, 50032) * healaxis.dat, start.dat, times_lost.dat - Add golden_record_sanity test suite to verify comparison system - Configure sanity test to run as fast test (no labels) The golden record system now properly compares all output files for classifier_fast while maintaining backward compatibility with other test cases that only compare times_lost.dat. šŸ¤– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- test/golden_record/compare_files_multi.py | 204 ++++++++++++++++++

Remove spline_3d_interpolation.f90 which was never used in production code - Remove corresponding test_spline_3d.f90 - Update CMakeLists.txt files accordingly - The module was infrastructure added but never integrated - Existing code uses libneo's interpolate module (albert, meiss) or custom implementations - Custom implementations (splint_can_coord, splint_boozer_coord) are tightly integrated with their modules šŸ¤– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- src/CMakeLists.txt | 1 -
