LARGE-SCALE FINITE ELEMENT ANALYSIS: AIMS, MANAGEMENT AND QA

Based on previous experience, guidelines are presented for accomplishing major linear quasi-static structural analysis of naval ships by means of superelement techniques generally available in proprietary finite element computer programs. The discussion includes h-version modelling techniques and the importance of ascertaining element accuracy characteristics in relation to the finite element discretisation. Attention is drawn to quality assurance procedures undertaken at each stage of the analysis. In particular examples are provided of applying a recently developed interactive 3D graphic quality assurance processor which has proved to be exceptionally effective in ensuring the integrity of the structural models. Reference is made to adaptive mesh refinement, basic concepts of the p-version of the finite element method and related a-posteriori error estimates. The potential is emphasised of p and h=p extensions to readily provide accurate converged results from subsequent detailed stress analysis using boundary conditions provided by large scale models.
