Overview
NuMagSANS is a GPU-accelerated computational engine for the simulation
and analysis of nuclear and magnetic small-angle neutron scattering (SANS).
The framework enables atomistic and micromagnetic SANS calculations,
including polarization-resolved channels, correlation functions,
and spectral decomposition.
NuMagSANS is designed as a deterministic single-run computational engine
with a clear execution pipeline and reproducible output.
