| 中文摘要: |
| 本文应用一种基于调和映射的移动网格方法计算非定常渗流,该方法将偏微分方程求解与网格移动算法分开,且需要在新生成的网格上插值更新解.本文通过计算一个关于梯度的控制函数,使得网格加密与希疏化是随着水力梯度的变化自动实现的.从而提高整体解的精度. |
| 英文摘要: |
| This paper applies moving grid method based on harmonic maps to calculate unsteady seepage,which delinks the PDE solver and the mesh-moving algorithm and then requires interpolating the solution on the newly generated mesh.In this paper,it makes the mesh refined or coarsened self-fulfilling based on the change of hydraulic gradient by calculating a monitor function on gradient so as to enhance the accuracy of the solution. |
