1、问题描述：土坝中存在一道粘土心墙，心墙的渗透系数远远低于周围土体的渗透系数，因此认为是不透水材料，要求计算在水位上升时土坝内的渗流情况。可分为三个步骤：1.心墙的渗流计算Config fluid Set fluid offGen zon brick p0 0 0 -10 size 20 1 10Gen zon brick p0 5 0 0 p1 15 0 0 p2 5 1 0 p3 9 0 5 p4 15 1 0 p5 9 1 5 p6 11 0 5 p7 11 1 5 &Size 10 1 5Group soilGroup dam ran x 5 7 z -5 0Group dam ran
