A circuit human body model for an indirect lightning strike analysed by means of an FDTD method

In this presentation, a simplified human body, stroked by a lightning touch voltage, is implemented via lumped elements and analysed through the finite-difference time-domain (FDTD) method. The results, so extracted, are compared with those of an electronic circuit simulator. Furthermore, the current induced to the human body in the vicinity of a lightning stroked object, is accurately calculated by the FDTD algorithm, which overwhelms the circuit modeller that is unable to simulate non-contact scenarios.
