Angular discretization

adaptive (“accuracy” selection & # sources)

adaptive (24 to 960 auto. varying within/between energy groups) adaptive multi-resolution Cartesian grid (auto. based on scatter fluence gradient) Phase space file for source model 37 groups (adaptive for the scatter fluence using an appropriate energy weighting function f(E))

Spatial discretization

adaptive multi-resolution Cartesian grid (“accuracy” selection)

Pre-calculated data as input

Prim. dose → 1 st scatter SCERMA → multiple scatter SCERMA

Prim. fluence → 1 st scatter source
