简介：柱体的垂直摆动与不同直径比率Dd/Dc和厚度比率td/Dc被3D学习(三维)在这份报纸开发的数字模型，并且通过2D与结果相比获得了(二维)数字模型。高顺序的迎风的计划被使用稳定计算，并且集中被多格子方法加速。2D和3D模拟结果之间的差别的质、量的分析与一个依附底部的磁盘在流动地特征和垂直地震荡的柱体的水动力学系数上揭示3D效果。液体领域上的3D效果主要在三个流旋涡的模式的意义被反映：x相对在2D模拟产生的旋涡在锋利的边附近在流动地上有更大的效果。在沿着轴的取向的片，沿着光线的轴的y比沿着环绕的方向的x，更在速度上显示光线的效果在磁盘的锋利的边附近比环绕的效果读了。旋转相互作用在水平飞机的液体的z在举运动期间是不足道的。基于2D和3D模拟结果，分开增加的集体系数和抑制比率的增加的政体的转弯的点被识别。直径比率Dd/Dc和厚度比率td/Dc详细被讨论。
