VortexStepMethod - v2.1.0

VortexStepMethod v2.1.0

Diff since v2.0.0

Changed

1. Core New Functionality: YAML Geometry Support

• New file: yaml_geometry.jl (290+ lines) — Complete YAML-based wing geometry loading.
• New structs: WingSectionData, WingAirfoilData, WingAirfoilInfo (with @with_kw macros).
• New function: load_polar_data() — Robust CSV polar data loading with error handling.
• New constructors:
  • Wing(geometry_file::String) — Create wings from YAML files.
  • Wing(settings::VSMSettings) — Create wings from settings.

2. Enhanced Settings System

• Renamed vs() to VSMSettings() constructor.
• Added convenience Solver(body_aero, settings) constructor.
• Improved settings structure and validation.

3. Comprehensive Test Infrastructure

• Split tests: Reorganized from monolithic files to modular structure (test/module_name/test_*.jl).
• New test module: yaml_geometry with test_load_polar_data.jl and test_wing_constructor.jl.
• Test utilities: test_data_utils.jl with shared helper functions.
• Test data: Extensive YAML and CSV test files in data.

4. Data and Examples

• New data sets: Complete TUDELFT_V3_KITE with CFD polars and literature results.
• Enhanced examples: Updated examples to use YAML geometry (e.g., pyramid_model.jl, V3_kite.jl).
• Real-world configs: Production-ready YAML geometry files for various kite configurations.

5. Core Module Improvements

• Path handling: Robust file path resolution for relative/absolute paths.
• Error handling: Comprehensive validation and graceful fallback to INVISCID mode.
• Memory management: Improved file I/O and cleanup in tests.
• Documentation: Added comprehensive docstrings and examples.
