A METHOD TO GENERATE MESH DEFORMATION PATTERNS FOR ALE FINITE ELEMENT FLOW ANALYSIS

ALE有限要素法による流体・構造相関問題の解析に用いるメッシュ変形パターンを汎用的に与える方法を開発した. 提案する方法は, 節点の移動量を節点変数とする有限要素ラプラス方程式を解き, その解から要素ごとの歪みを計算したのち, 歪みの大きさに応じた重みづけをし直した方程式を再び解いて最終的な変形パターンを得る, というものである. この方法により, 要素の歪みが局所的に集中することの少ない良好なメッシュ変形パターンを領域形状や物体の数によらず汎用的に生成することができる.
