メッシュ規模に依存しない有限要素法高速ポストプロセッサ

抄録

This paper describes a new visualization technique for three-dimensional large-scale finite-element analyses, whose visualization speed is independent of mesh size. Once an analysis shape is defined, a small-scale mesh with uniform distribution of element sizes is created using an automatic mesh generation technique. The mesh is named here a virtual finite-element model and used only for the purpose of visualization. Then the mapping between the virtual FE model and the analysis shape and the mapping between the virtual FE model and an actual FE model are established. Analysis conditions and analysis results can be visualized using the virtual FE model interactively on any graphics hardware. We developed a postprocessor, and applied it to a large-scale heat conduction problem. It was demonstrated that this technique can provide a fully interactive visualization environment.
