HydroChrono 0.3.1 delivers major refactoring and performance improvements across hydrostatics and radiation damping, adds profiling and smoothing features, and introduces full Linux build support.

Highlights

  • Refactored hydrostatics and radiation damping modules for clarity, safety, and maintainability
  • Unified Eigen-only math backend; resolves vectorization/SIMD compatibility issues
  • Refactored & Parallelized radiation damping convolution integral (5× faster)
  • Added Savitzky–Golay smoothing and tapering for more stable convolution results
  • New --profile flag for runtime performance breakdowns
  • Auto-enable Irrlicht GUI when IrrlichtDir is configured
  • Fixed and verified Linux builds
