On the Modelling of Field-to-line Coupling Inside a Lightning Struck-Aircraft 2001-01-2891

This paper discusses the features of different field-to-line coupling simulation models to be used for the transient analysis of the EM induced effects of the direct lightning interaction with aircraft. The choice of one model is suggested by the quasi-magnetostatic nature of the lightning interaction problems, which generate numerical inaccuracy in the calculation of the electric field solution inside the computational domain. It is demonstrated that the use of the field-to-line coupling model based on the use of the magnetic field components allows to avoid numerical inaccuracy.
