模型功能描述

在进行地下水模型模拟时,通常将研究区域含水层离散为网格单元,网格剖分往往只顾及研究区域的空间几何特征,对属性数据考虑不足;其次,在进行地下水模型模拟时,模拟的外界条件是变化的,而模型模拟过程空间离散网格一成不变,初始建立的网格不能很好的反映属性数据的变化特征。

针对地下水模型模拟过程中存在的上述问题,开展了在网格剖分时引入属性特征约束条件,通过模型模拟的属性特征约束构建网格剖分时的尺寸控制场,开展基于几何和属性特征约束的三角网剖分算法研究。并进行不同空间离散网格条件下的地下水模型模拟模型,验证了基于几何和属性特征约束下的三角网生成算法在地下水模型模拟的优越性。另外针对模型模拟外部条件的改变,综合考虑水文地质模型的几何空间特征和内部属性数据的动态变化过程,通过特征约束集合映射与更新来开展地下水模型模拟实验。

模型的功能具体包括以下三个部分:

1)基于几何和属性特征约束的二维`AFT`网格剖分

基于推进波前法,综合考虑几何特征约束和属性特征约束,在几何特征约束的基础上,引入属性特征约束来获取网格剖分时的背景网格,构建网格剖分尺寸控制场进而控制网格单元大小,最终生成综合考虑了几何和属性约束的网格。

2)不同特征约束的离散网格

地下水模型数据文件配置方案,开展不同特征约束网格下的地下水模型模拟。

3)动态约束

对地下水模型模拟过程中模拟条件的变化,获取约束条件改变下的离散网格,进行模型模拟实验
