Optimization of Cascade Simulation Process Using Spatial Parametrization

Simulation of neutrino telescopes like IceCube, Baikal-GVD, KM3NET/ARCA is a long multi-stage process. NTSim is a framework efficiently chaining different stages of the simulation. Full Monte Carlo modeling of electromagnetic and hadron cascades usually consumes a lot of computational resources. In this contribution we present an efficient cascade parametrization of NTSim which allows to significantly reduce computation time and validate it against the full cascade modeling.
