摘要
提出针对舱口角隅处网格的自动有限元精细划分方法,粗细网格使用过渡单元平滑过渡,自动创建规范要求的几种导角和开孔,并对部分筋单元进行板元化。
An automatic FEM mesh refining algorithms for the hatch corner is presented, by which the sparse mesh and refined mesh can transit smoothly with transition element, several kings of filleted corners and holes can be created automatically according to the criterion of CCS, and the specified bar elements can be replaced by shell elements. The result shows the method can achieve the refined FE analysis perfectly needed by check of the strength and fatigue, resolve thee fussy and non-system work by hand.
