Study on the step voltage caused by lightning current with postured voxel-based human body models

This paper studies the effect of the step voltage due to a lightning strike on the human body. Two voxel-based human body models with standing and walking posture were developed and integrated into simulation models to compute the current density distribution in the human body shocked by the step voltage. In order to speed up the transient simulation, the reduced c technique was used, leading to a speedup factor of around 20. In the paper, the trade-off between speedup and error when using the reduced c technique is discussed, and simulation results are presented in detail.
