1. I need to be efficient

The multigroup (G), DOM (S N

), cross section expansion (P N

) method converges to an

analytic solution of the LBTE for G, N → infinity and no volume averaging is expected for fine spatial discretization (N vox

→ infinity)

BUT I need to be efficient

and since t~ G x M x N vox (x #iters. x order of legendre exp.), even if I have the perfect finite differencing algorithm for solving the system of equations,

I need to reduce G, M, N vox
