Lightning effects simulated with efield®

Lightning is a major threat to any complex system containing sensitive electronic equipment. Simulations are preferably performed in the time domain. Field penetration into the interior of an aircraft and the corresponding induced wire currents are examples of studies that can be performed with efield®.
