The final result of the FluDAG testing is that we are confident for the range of inputs tested that we get equivalent results to Fluka for both simple and complex geometries.
The testing performed in the complex ATIC geometry case shows that for complex geometries we agree well. The 3D results from Fluka USRBIN scores show near equivalence between the native geometry and the DAG geometry, all particle types scored show agreement to well within the 3\(\sigma\) error bounds.
