| 摘 要： | 为解决非结构网格下诸多水流模型计算所得流场(流速、水位和通量等)在后处理图中显示凌乱(不利于反映流场特征)的问题,运用反距离加权法对非结构网格的流场结果进行插值,得到任意目标结构网格下的流场值.该方法应用于实际工程中,插值结果与原计算结果吻合较好,满足工程精度要求.

| Abstract: | The computing result(velocity,water level and flux,etc) of a lot of numerical models which are based on unstructured grid is usually disorder in postprocessing figure,such as the results of velocity,water level and flow,and it's unfavorable to show the characteristics of the flow field.For solving this problem,a interpolation method called inverse distance weighted is applied to treat the vectors of flow field,so as to obtain the results based on structure grid.This method is applied to the projects,and the... |
