基于 OPS 和拓扑交换的离心泵网格质量提高算法
Mesh quality improvement for centrifugal pump based on OPS and topological swapping
摘要
Abstract
A mesh quality improvement strategy combining OPS and topological optimization was firstly putted forward to overcome the existing defect that can't improve bad elements with all their vertices on the boundary in OPS.According to the sharing form of edge (or face)and its adjacent element,the approach applied different topological optimization methods.The topological correlation of mesh after optimization rather than the element quality in connected region was considered.In this way,this kind of element was transformed into non-full-boundary element.Examples show that the approach shows better advantage in boundary and whole mesh quality than OPS.Numerical results show that comparing with Freitag algorithm,the proposed algorithm is more successful in eliminating poor dihedral angles at both extremes.And the combined algorithm shows better advantage on boundary and entire quality improve-ment for centrifugal pump over OPS.关键词
