Simulation plays an increasingly important role in evaluating system performance when subjected to Electromagnetic Environmental Effects (E3) and for investigating strategies for protection. Lightning strike simulation is one of the key applications in this area, which can seem daunting given the multi-scale and multi-physics nature of this fascinating phenomenon. Modeling of complex composite materials and susceptible features such as seams and cables are crucial details to consider.

In this eSeminar, we will show how EM field simulation can provide insightful information with respect to lightning attachment/zoning analysis as well as transient current and magnetic field immunity of relatively large platforms such as aircraft. We will demonstrate definition of the source excitation and boundary conditions, modeling of the lightning channel entry and exit points, and other fundamental aspects of the model setup. Compact models (see our eSeminar on applications of Compact Models) for modeling thin materials, wire meshes and seams, as well as field-cable co-simulation will also be discussed.
