摘　　要：针对常规自适应有限元网格生成方法对分析对象的特征描述能力不足 ,提出了基于特征的自适应有限元网格生成方法。通过特征定义及特征点、线、域搜索 ,可实现基于特征控制的自适应有限元网格密度分布。In accordance with the inadequate feature describing ability of the conventional adaptive finite element mesh generating method, a feature based adaptive finite element mesh generating method is proposed in the present paper.With this method, a feature control based adaptive finite element mesh, by feature definition, search of feature point, line and region, the feature based mesh density control can be realized.
