Neural equal-area scattering surrogate for He-Ar preserves QD, Qμ, RCS and related quantities within 1.5% and reproduces DSMC diffusion and shear tests within 1-2% normalized error.
A transport-augmented objective adds batch estimates of QD andQ µ: LQ = 1 NE NEX ℓ=1 QD,θ(Er,ℓ) QD,ref(Er,ℓ) −1 2 + Qµ,θ(Er,ℓ) Qµ,ref(Er,ℓ) −1 2
