Abstract
The finite-element method is very powerful and flexible to model complex geometries with computers, because of region of interest can be subdivided into finite elements accurately. The advantages and drawbacks of the finite-element method will be the focus of the rudimentary investigation presented in this report. Especially, the requirements in terms of computational effort and computer memory storage will be investigated with respect to Nuclear ElectroMagnetic Pulse (NEMP) research requirements, i.e., with configurations frequently found in NEMP research such as coupling and interaction studies, simulator design and sensor design. Such configurations are often three-dimensional and of intricate geometry. It is found that with present day computer capability it is not yet possible to solve real-life three-dimensional geometries with the finite-element method, because of the memory requirements needed to store the resulting system of equations.
