摘要

在有限元素電腦輔助分析中，電腦輔助設計模型建制完成後往往需要經過複雜前處理才可以進入有限元素軟體內分析，在轉換的過程中需要考慮到軟體的因素、硬體的限制、檔案的正確性等等複雜的問題。本研究在於探討幾何的最佳化，來幫助計算的結果收斂性與效率的提昇，研究過程中藉由電腦輔助設計與電腦輔助工程分析的系統化整合流程的應用，來達到此一研究的目的。

During the finite element analyses, geometry imported form various CAD software systems need to be meshed in pre-processor software with great efforts. How to generate high-quality structured meshes efficiently has been an important issue in the finite element analysis process. In this study, the applications and investigations of structured meshes in complex geometry are discussed and systematic integration processes are proposed through real case applications.
