Abstract :
In order to increase the stealth of ships, the magnetic anomalies they create are minimized by using deGaussing systems. To improve the deGaussing process, the French Navy has requested a numerical model of the magnetic anomalies created by ships. The authors present an overview of their work in the finite-element modeling of ships, and the original software tools they developed, used, and implemented in the Flux3D finite-element program. These tools include surface and line elements, open-boundary modeling using transformation, and the use of the reduced-scalar potential. Finally, the complete finite-element modeling of an actual ship using Flux3D is presented
