Abstract
An apparatus for conducting an engineering analysis of a structural product is provided. The apparatus produces a computer-aided design (CAD) model of the structural product including component parts joined by fasteners and produces a finite-difference time-domain (FDTD) model of the structural product from the CAD model. The apparatus assigns one or more electrical properties to a mesh of elements representing the component parts and fasteners, and performs a finite-difference time-domain analysis on the FDTD model with the one or more electrical properties assigned, and with the FDTD model exposed to simulated lightning, to predict an impact of lightning on the fasteners and therefrom generate a corresponding prediction. The apparatus produces an output based on the corresponding prediction that indicates one or more levels of the impact of lightning on the fasteners and displays the output to facilitate design or manufacture of the structural product.
