Abstract
A curvilinear stochastic finite-difference time-domain (S-FDTD) methodology is presented in this paper for the systematic analysis of lightning-induced fields over rough terrains with statistical uncertainties. The novel 3-D technique stems from a covariant/contravariant formulation which can profitably handle the variation of specific parameters during a single run. To achieve further acceleration, graphics processing units (GPUs) with large core densities are utilized, while a set of realistic setups is addressed for the validation of proposed algorithm.
