Work out optimization in the induced electromagnetic field calculation due to a lightning stroke

Abstract

In the electromagnetic field work out, due to indirect lightning discharge, the consumption of computational resources is essentially in the numerical integration of the Maxwell equations. These equations are solved in each discretized point for each time step because the work out of the field involves the inverse of the distance that’s powered by 2, 3, 4 and 5; additionally its depends on the wave incident angle, which varies point by point, so it is impossible to interpolate, in a traditional way, intermediate data to optimize the calculus. It is proposed here the implementation of a parabolic space interpolation to reduce the computational needed resources; the compromise is the electromagnetic field calculation in the minimum time limiting the error to 0.2%. It is looking for the optimum points, methodologically, to implement this interpolation by checking the results against the obtained ones without the omission of any point, so it is considered that this strategy is a good option in the electromagnetic field optimum calculation
