Extended usage of a Modern Product Model in Finite Element Analysis

Abstract
Finite element method (FEM) has been an engineering tool for decades, and is beginning to replace also the more simple methods used traditionally for structural analysis in the initial phases of a ship design process. However, naval designers still seem to be lacking a practical tool for seamlessly integrating this sophisticated technique with other aspects related to iterative design cycles and the 3-D models applied. This paper will present the approach currently used in SURMA (Survivability Manager Application). The general principle behind the ideas described here lays in establishing a real two way communication between a modern ship product model and a full 3D finite element analysis software. The product model acts as a backbone for the structural analysis purposes, offering a highly detailed basis for the FE analysis, in terms of both the structures as well as the loads. The presented approach enables the full utilization of both tools when conducting structural analysis using finite element method.
