Monte Carlo simulation of airborne infection risk in indoor environments using the ASHRAE Standard 241 Wells-Riley framework. Based on the methodology in Jones et al. (2025).
Python/ -- Reference implementation (numpy, scipy, matplotlib).
See Python/README.md for full documentation.
C++/ -- High-performance C++17 port (~20x faster).
See C++/README.md for build instructions, benchmarks, and
validation results.
